The Qin and Han Dynasties were the first period of unification in Chinese history，The rulers with great talent and sagacity often use inspections to promote morality in remote areas within their territory、Strengthening rule。Shandong is an important area for the Qin and Han emperors’ eastward tour，Documents record Qin Shihuang、Emperor Wu bet365 live casino games Han Dynasty once visited Mount Tai、Zhifu in Yishan and Qi’s “Eight God Lords” belief system、成山、Langya and other places，Sacrifice to the gods and build something。

As a sacrificial site for the "Lord bet365 live casino games Four Seasons" among the "Eight Gods", the Langyatai ruins are located in the southern part of Huangdao District, Qingdao City, Shandong Province，East、South、The three northern sides are bordered by the sea。"Historical Records" records that Qin Shihuang once "built Langyata" here，Standing stone carvings，Ode to Qin De，Ming Deyi”，After Qin II、Emperor Wu bet365 live casino games Han Dynasty and others also visited here，Qin Langya carved stone was found here。The Langyatai site currently contains large rammed earth building foundations and many other remains，Since the 1970s，After many archaeological investigations、Exploration and rescue cleanup work，In 2013, it was announced as a national key cultural relics protection unit。

Since 2019，Prepared to cooperate with the site protection planning，Approved by the State Administration of Cultural Heritage，Shandong Provincial Institute of Cultural Relics and Archeology、Qingdao Cultural Relics Protection and Archeology Institute and Qingdao Huangdao District Museum formed a joint archaeological team，Conducted active archaeological excavation of Langyatai site。The excavation areas are located at the “Datai” bet365 live casino games main peak、Multiple locations such as "Yaogou" in Shannan and "Tingzilan" in the southeast of Dataai。

Through continuous systematic exploration，Scale of Langyatai ruins、The layout and main ruins are basically presented，Confirmed that the main body of "Datai" is the foundation bet365 live casino games high platform building in the Qin and Han Dynasties，Discover the room under the stage、Important ruins such as drainage facilities，With the Qin Dynasty carved stones discovered earlier，It can be basically presumed that it is the Langyatai built by Qin Shihuang。Distribution area of ​​brick and tile kilns found in the kiln trench under the south slope，A large number of relics were unearthed，Provides a more accurate basis for the periodization of building materials on Taiwan。The discovery of Tingzi orchid along the coast is relatively large、Unique architecture bet365 live casino games Warring States period，Characteristics of Qi，It is of great value for tracing the historical origins of Qin Shihuang’s eastward tour of Langya and the construction of Langya Terrace。While excavation，The archaeological team also conducted a large number of investigations in and around the Langyatai site、Exploration，Important gains were also made。

　　The high-rise buildings are bet365 live casino games-scale and magnificent

Confirmed by archaeological excavation，Located in the center of Langyatai ruins，The main body bet365 live casino games "Datai" located on the top bet365 live casino games mountain at an altitude of 183 meters is the foundation of a high platform building from the Qin and Han Dynasties。The buildings after the Han Dynasty were ruined，Li Daoyuan bet365 live casino games Northern Wei Dynasty's "Shui Jing Zhu" records the remains bet365 live casino games foundation site: "Three floors bet365 live casino games platform base，Three feet high，Superior Pingchang，More than two hundred steps per side，Guangwuli。”Measurement by recovery，The uppermost platform is about 61 meters long from east to west、About 39 meters wide from north to south。Although the rooftop building cannot carry out work due to the occupation of existing facilities，But through continued excavation，The west side bet365 live casino games platform base is basically fully exposed，The thickness bet365 live casino games wall can be observed to be about 8 cm、Uniform ramming layer，Hard soil，Smooth ramming surface，Extremely high quality of project。

The northwest corner bet365 live casino games platform has collapsed，The southwest corner is better preserved，A stage step made of hollow bricks was found near the southwest corner。A room attached to the platform base was found in the south center bet365 live casino games platform，The room is composed of a recessed space on the platform and surrounded by rammed earth walls，It is speculated that you should sit east and face west，About 18 meters wide，Due to the complete destruction bet365 live casino games west side，Unknown depth。No trace of tiles on the indoor floor，Northeast corner、There are wall tiles remaining in the southwest corner。A stone floor drain facility was found in the north bet365 live casino games ground，The plane is rectangular，Side length 1.2—1.4 meters，Multiple rectangles、Made of trapezoidal and triangular stone slabs，Incline downward from the four sides to the middle，There is a square hole drilled into the square stone slab in the middle。A doorway was found in the northeast，There are square pillar foundation stones at the four corners，To the north bet365 live casino games doorway, three stone pillar foundations are found parallel to the wall bet365 live casino games rammed earth platform，It is presumed to be a corridor with eaves on it。

A group of drainage facilities discovered at the Langyatai site，Parallel to the edge bet365 live casino games rammed earth platform，By water inlet、Composed of underground pipes and stone floor drains，Drainage from north to south。The water inlet is on the west side bet365 live casino games corridor north bet365 live casino games room，Consists of a ditch dug out of rammed earth and a stone pool。The bottom bet365 live casino games ditch is tilted，High in the north and low in the south，The pool is located in the south bet365 live casino games ditch，Stone paving at the bottom，The southern end bet365 live casino games stone slab is connected to the underground pipe。A square brick with holes was found at the junction bet365 live casino games pool and ditch，Can filter water discharged into pipes。The pipe consists of one big end、A small cylindrical pottery tube is formed by connecting each section，Two columns side by side，The remaining length is about 26 meters。The pipes are pre-buried during the construction process，There is generally a layer of reddish-brown dense clay between the pottery pipe and the rammed earth，May be used for reinforcement and anti-seepage。The lower end bet365 live casino games stone floor drain found in the north bet365 live casino games room is connected to the pipe，Because it is located downstream bet365 live casino games water inlet，After the dirt is discharged into the pipe, it can be flushed more thoroughly with upstream water。Except for the west side bet365 live casino games platform，A section of pottery pipe was also found at a lower level in the northeastern part of Datai，Ceramic pipes here are generally larger in size，Three columns side by side，Drainage from south to north，It is speculated that there should be an independent main building on its south side、Important outbuildings with high drainage requirements。

"Datai" South、Long strips of rammed earth discovered in Beijun，The rammed earth on the south slope is wider，The rammed layer is inclined，Presumed to be the road up the mountain。Langyatai Mountain is rich in rocks and little soil，Such a huge building base，The soil basically needs to be transported from the mountains，Get soil、Transportation、The ramming and construction process requires a huge amount of manpower and material resources。In "Historical Records: The Chronicles of Qin Shihuang", it is said that "30,000 households moved to the first part of Guizhou under the Langyatai"，Twelve years old again，Records of “Langyatai”，The "Datai" base site discovered by archeology is huge、Construction work of extremely high standards，Corresponding to the document。Also，Signs of later reconstruction were also found during the excavation，Including the room under the stage was abandoned and filled with rammed earth，Underground pipes were blocked and replaced by open ditches paved with tiles, etc.。According to layer relationship，The reconstruction should be no later than the Western Han Dynasty。Historical data records that the First Emperor built the throne and the Second Qin Dynasty、Emperor Wu bet365 live casino games Han Dynasty also visited Langya eastward，The Four Seasons Lords bet365 live casino games Ritual Temple，Reconstruction or related。

　　Rich types of bet365 live casino games components with distinctive features

 Thick collapsed accumulations are common under the surface soil layer of “Datai”，A large number of relics were unearthed，Mainly made of tube tiles decorated with cord patterns and tile rib patterns、Slab tile，A round tile decorated with cloud patterns and the words "Long Live Qianqiu"，Plain or patterned floor tiles and processed、Rectangular stone strips、Stones, etc.。The unearthed relics are basically building materials，It belongs to the Qin and Han Dynasties，Reflecting the large size bet365 live casino games building on the top bet365 live casino games mountain、High level。Then，Are a large number of building materials produced nearby or shipped from afar？

The discovery bet365 live casino games kiln site area solved the problem bet365 live casino games origin of this batch of building materials。Through careful archaeological exploration，We found that the kiln site area is mainly located at the southern foot of Langyatai、Near the deep ditch commonly known as "Yaogou" by local villagers。Currently 9 kiln sites have been excavated，Concentrated distribution arrangement，Both are northwest-southeast，Close in scale，About 8 meters long、About 3 meters wide。The kiln is composed of operating room-fire chamber-kiln room-flue，The plane bet365 live casino games fire chamber is triangular，The kiln chamber is rectangular，Three round or semi-circular flues at the end。A northeast-southwest ditch was found on the north side bet365 live casino games kiln site area，Downstream leads to the modern "Kiln ditch"，A large number of relics were unearthed in the ditch，It is observed that most of them are kiln waste。

A large number of broken tiles were unearthed in and around the kiln site、Dong tile、Circular moiré tile、Plain square bricks and ceramic pipes, etc.，The shape is basically consistent with that found in Dadai，There are many deformed people among the relics，In addition, there are a large number of sintered kiln wall fragments。The remains of a large semicircular tile with Kui patterns found，Restored diameter exceeds 50 cm，With Shaanxi Qinhan Yueyang City、The shapes of those excavated from the bet365 live casino games and Han palaces and other sites such as the Jiangnu Stone in Suizhong, Liaoning are similar，The era is bet365 live casino games，When used in extremely high-level buildings。Accordingly，We speculate that these pottery kilns are brick and tile kilns used for firing building materials in the bet365 live casino games Dynasty。It is worth mentioning，No tiles with the words "Long Live Qianqiu" were found in the kiln site area，May indicate that it is of later date。The excavation of these kiln sites provides empirical materials for judging the age and staging of Taitai buildings。

On the hillside between Yaogou and Dadai，Many rammed earth areas were discovered through exploration，Learned through dissection，rammed earth soil、The earth color and thickness bet365 live casino games rammed layer are consistent with those bet365 live casino games platform，The rammed layer is inclined。Connect these rammed earth distribution areas，The road up the mountain at that time can basically be restored。

　　Langyatai and Qi Langya City and bet365 live casino games Langya County

The State of Qi in the Eastern Zhou Dynasty，Langya’s status is very important。"Mencius: King Hui of Liang" states: "In the past, Duke Jin of Qi asked Yanzi: 'I want to observe the imperial seal that was transferred to the court'"，Follow the sea and south，Put in Langxie，How can I practice to compare with the view bet365 live casino games former kings？’” words，"Warring States Policy·Qi Ceyi" records that Su Qin lobbied King Xuan of Qi and said that "there is Mount Tai in the south of Qi"，There is Langya in the East，There is Qinghe River in the west，Bohai Sea in the north"，It can be seen that Langya is the coastal fortress of Qi State、Eastern Important Town。

Southeast of Langyatai during archaeological survey、A dense accumulation of tiles was found on the coastal platform called "Tingzilan" by local people，Speculated to be related to ancient architecture，Thus a larger area of ​​excavation was carried out。The unearthed relics are obviously older than "Datai"，It is speculated that the remains date from the Warring States Period，The discovered ruins mainly include the foundations of corridor-style buildings、Yuan wall foundation groove, etc.。The existing length bet365 live casino games corridor-style building foundation exceeds 90 meters，About 5 meters wide from north to south，The west is destroyed by modern buildings。Dense accumulation of tiles was found in the ditches on the north and south sides bet365 live casino games foundation site，Part bet365 live casino games tiles、The roof tiles are completely preserved and interlocked，Should be the original accumulation of collapsed buildings。Archaeologists speculate that there was originally a "corridor-style" building with tiled roofs on both sides，When the building collapses，The roof tiles on the north and south sides、The roof tiles etc. slipped into the ditches on both sides。A rectangular foundation trench was found on the east side bet365 live casino games corridor-style building foundation，The foundation trench is paved with broken pottery fragments and soil alternately，Supposed to be the remains of a courtyard wall，The courtyard is close to the sea，Only its southwest corner remains。

This group of buildings in "Tingzilan" is in poor preservation condition，But through a wide area and a large number of unearthed relics，You can still see its extraordinary scale。The construction date is the Warring States Period，The style of relics mostly reflects the characteristics of Qi State，May have a higher level and special ritual significance，Maybe it’s related to Qi’s management of Langya，It is of great significance for tracing the historical origins of bet365 live casino games Shihuang’s eastward tour of Langya and the construction of Langya Terrace。

After Qin unified the six kingdoms，Establish thirty-six counties，Langya County is one of them，Make Langya County the administrative seat。Historical records indicate that Emperor Qin Shihuang built Langyatai and moved 30,000 households there，Migrant population、The establishment of counties is actually the most effective means of local control。While excavation，The archaeological team conducted a detailed regional systematic survey and a relatively comprehensive exploration around the Langyatai site，Compare past work results，Strive to find out the distribution of ancient ruins in the area around Langyatai，Pay special attention to finding relevant clues about Langya County。Passed survey，The relics bet365 live casino games Qin and Han Dynasties near today's Langya Town are rich and concentrated，There should be a larger scale、Higher level settlement，Maybe it was an important foothold for the Qin and Han emperors during their eastward tour of Langyatai，When the sea level in ancient times was higher than modern times for a long time，It can be connected to Langyatai through the Jijialing first-line highland，Perhaps related to Langya County。

　　New discoveries are bet365 live casino games

The main body bet365 live casino games Langyatai site is large-scale high-level buildings from the Qin and Han Dynasties，It is a royal project built by Qin Shihuang to "promote 30,000 households"，Has an important position in the history of Chinese architecture，Archaeological excavations provide new materials for the study of high-level buildings, especially high-level buildings during the Qin and Han Dynasties。The unearthed architectural relics mainly involve the Warring States Period、Three periods of Qin and Western Han Dynasty，Reflecting era and cultural differences，It is a rare physical material for studying the periodization and dating of building materials in the Warring States, Qin and Han Dynasties。

The Qin and Han emperors’ inspections and sacrificial activities along the coast of Shandong had strong political implications，The Eastern Patrol is an important means to strengthen the dynasty’s control over the eastern region。Therefore，The dynasty has mastered the right to worship the original local gods，As a result, we have a deeper grasp bet365 live casino games power to rule and dominate this region。As the first unified dynasty in Chinese history，In addition to the original sacrificial system bet365 live casino games Qin Dynasty，Absorb、Inherited and integrated the sacrificial traditions of Eastern countries。The "Eight Lords" Sacrifice is an important sacrificial system in Qidi，Reflects the relationship between man and nature and the unique concept bet365 live casino games universe in the eastern coastal area，By Qin Shihuang、Attention and acceptance by Emperor Wu bet365 live casino games Han Dynasty。After becoming emperor of Han Dynasty，Although the "Eight Lords" sacrifice was abolished in the national ceremony，But the deep concepts contained in it were inherited by the Central Dynasty，Become an important guiding ideology in the national sacrificial system。The differences in cultural connotations of sites in different periods also reflect the evolution bet365 live casino games sacrificial system from the Warring States to Qin and Han Dynasties to a certain extent。

As an important place where the bet365 live casino games and Han emperors visited Shandong，A series of new archaeological discoveries at the Langyatai site fully reflect the important position of today's Shandong area in the unified country of bet365 live casino games and Han Dynasty，It also reflects the important role of Qilu culture in the formation of Chinese civilization。Therefore，Protection of ruins、Interpretation and utilization have important historical and practical significance。
