The terrain in ancient Gansu was complex、Strange landforms、Rich resources、Many ethnic groups、Convenient transportation inside and outside、Close exchanges between East and West，Created the prosperity of ancient Gansu bet365 kentucky bonus code，It also makes Gansu one of the important birthplaces of Chinese civilization。Among the many cultural types that are rich and colorful with obvious local characteristics，Siwa bet365 kentucky bonus code is a cultural relic with obvious regional attributes and unique characteristics in Gansu during the Bronze Age。

　　Discovery and Distribution

1924，Swedish geoarchaeologist Andersen discovered a unique bet365 kentucky bonus code in Siwa Mountain, Yaxia Market Town, Didao County, Gansu Province (now Lintao County, Gansu Province)，And put forward the six-phase theory of ancient Gansu bet365 kentucky bonus code in "Gansu Archeology"，The "Siwa Period" is impressively listed。1945，Xia Nai presided over the excavation of the Lintao Temple Washan site，Major discovery made，Revised and improved the previous understanding of Andersen。Subsequently，Xia Nai formally proposed the concept of "Siwa bet365 kentucky bonus code" in "Excavations at Lintao Siwa Mountain"。Xia Nai identified the owner of Siwa bet365 kentucky bonus code as Di Qiang，Many scholars have different understandings of the specific ethnic groups of Siwa bet365 kentucky bonus code，But generally I still agree with Xia Nai’s statement。Therefore，Regard Siwa bet365 kentucky bonus code as the archaeological remains of the "Xirong" bet365 kentucky bonus code of the Di and Qiang system，Almost a consensus among academic circles。

Judging from the current archaeological surveys and excavations，Siwa bet365 kentucky bonus code is mainly distributed in the central and eastern regions of Gansu Province, east of Lanzhou City, Gansu Province，Its distribution range does not exceed the Lanzhou line to the west，Go northeast to Qingyang, west of Ziwu Ridge、Pingliang area，Go southwest to Lintan in the middle and upper reaches of the Tao River、Zhuoni and other counties，Go southeast to Xihe in the Xihan River Basin、Li County and other areas，To the south you can reach Dangchang in the Bailongjiang River Basin、Wudu、Wen County and other places。From a water system perspective，Siwa bet365 kentucky bonus code should have originated from the upper reaches of the Tao River，Then develop eastward along the Tao River，Arrived at the upper reaches of Jinghe River in eastern Gansu and Qianxi in western Shaanxi、Where the Wei River meets，Developing northward to the Zhuanglang Hulu River Basin，The south reaches the upper reaches of the Xihan River and the Bailong River Basin。

The sites that have been determined to belong to the Siwa bet365 kentucky bonus code are basically all in Gansu，Contains approximately 5 kilns、Building address 20、460 tombs、700 ash pits。These sites have been excavated by archeology，There are also some discovered through investigation。The sites that have been excavated include the Siwashan site in Lintao County、Liujia Ruins in Zhuanglang County、Xujia Nian Site in Zhuanglang County、Lanqiao Site in Xihe County、Dazuping Ruins in Zhuoni County、Nine Station Sites in Heshui County、Li Ya Site in Qingshui County、Min County Zhanqi Site、Dabu Baituliang Site in Zhuoni County、Mogou Site in Lintan County、Anguo Town Site, Kongtong District, Pingliang City。The ruins discovered after investigation include the Sunping ruins in Wudu District, Longnan City、Renjiaping Site, Wudu District, Longnan City、Li Ya Tombs in Xihe County、Zhujiadawan Site in Zhuanglang County、Lijiazui Site in Zhuanglang County、Shiqiya Tombs in Lintan County、Yangdai Site in Zhangxian County。

Judging from the current archaeological excavation results of Siwa bet365 kentucky bonus code，No clustered residential address，The tomb information is relatively rich。The representative sites that have undergone formal archaeological excavation include the Lintaosi Kushan site、Zhuanglang Xujia Nian Ruins、Heshui Nine Station Site、Lintan Mogou Site、Xihe Lanqiao Ruins、Min County Zhanqi Site。

The Siwa bet365 kentucky bonus code of the above sites is generally similar，But there are some small differences。The shadow of Qijia bet365 kentucky bonus code can be seen in Lintan Mogou Cemetery and Minxian Zhanqi Cemetery，In particular, there are a large number of Qijia bet365 kentucky bonus code tombs at the Mogou site in Lintan，The mixed Siwa bet365 kentucky bonus code tombs are deeply influenced by the Qijia bet365 kentucky bonus code。Although some Zhou-style pottery was discovered at both the Heshui Jiuzhan Site and the Xujia Nian Site，But the proportion is lower，Indicates that there is a certain connection between Siwa bet365 kentucky bonus code and Zhou bet365 kentucky bonus code，But the influence of Zhou bet365 kentucky bonus code is limited。Also，The burial customs reflected in the Jiuzhan Cemetery in Heshui have certain similarities with the tombs of Qin bet365 kentucky bonus code。Although Siwa bet365 kentucky bonus code and foreign cultures interact and influence each other，But in terms of funeral traditions that can reflect deep spiritual and cultural identity，Siwa bet365 kentucky bonus code still shows a very obvious sense of cultural identity of its own ethnic group。

　　Types and installments

Based on the existing Siwa cultural heritage site，Academic circles have previously divided Siwa bet365 kentucky bonus code into two major types: Siwa type and Anguo type。Zhao Huacheng divided Siwa bet365 kentucky bonus code into three major types: Siwashan type、Lanqiao—Xujia Nian type and Jiuzhan type。This understanding has been widely recognized by the academic community。

The Siwa bet365 kentucky bonus code existed roughly between 1400 BC and 700 BC，Approximately equivalent to the mid-Shang Dynasty to the early Spring and Autumn Period。Currently, academic circles roughly divide the Siwa bet365 kentucky bonus code into three phases，roughly corresponds to the middle and late Yin and Shang Dynasties、Early, middle and two weeks of the Western Zhou Dynasty。The above three major types of Siwa bet365 kentucky bonus code were all discovered in the first phase，The Siwashan type is the earliest，Then the Lanqiao-Xujia Nian type appeared，The nine-stop type appears last。Lanqiao-Xujia Nian type and Jiuzhan type continue to develop in the second phase，The Sikubo Mountain type has basically disappeared。The third issue is here，mainly retains the nine-station type，Lanqiao-Xujia Nian type is gradually disappearing。

During a period of about 700 years，Siwa bet365 kentucky bonus code and Yin Shang bet365 kentucky bonus code、Liu Family bet365 kentucky bonus code、Pre-Zhou bet365 kentucky bonus code、Xindian bet365 kentucky bonus code、Kayo bet365 kentucky bonus code、Zhou Wenhua、Qin bet365 kentucky bonus code and others have coexisted for a long time，There are existing conflicts between each other，Another interactive blend，Jointly promoted the "Chineseization" of the ancient nations in the Guanlong region during the pre-Qin period and the construction process of the early Chinese national community。

　　Characteristics and Region

Siwa bet365 kentucky bonus code in Taohe、Jinghe、Weihe、The Western Han River and Bailong River basins have existed for more than 700 years，Although it also has certain exchanges and mutual learning with other cultures in Guanlong and surrounding areas，But it still formed and maintained some of its own cultural development characteristics for a long time。Based on the overall cultural style displayed by each site of Siwa bet365 kentucky bonus code，Combined with existing research results in the academic community，We can summarize the main characteristics of Siwa bet365 kentucky bonus code into the following aspects。

First，The shape of Siwa bet365 kentucky bonus code pottery，Represented by the saddle-shaped mouth amphora，Flat-mouth jar with ventral ears、Bao Zu Ge、One-ear cup、Tripod-shaped tripod、The coexistence of long-necked, round-bellied, double-eared pots。Siwa bet365 kentucky bonus code pottery is mostly sand-filled pottery，The quantity of clay pottery is small。The pottery body is mainly orange and reddish brown，A few are gray and black。Use with many plain surfaces，Some pottery has painted surfaces、Additional stacking、Engraved patterns and holes，There are engraved symbols similar to words on some pottery。Typical pottery generally shows the evolution pattern from short and fat to thin and tall，We can use this to initially judge the evolutionary sequence of the same type of pottery。Siwa bet365 kentucky bonus code pottery is mostly handmade using the clay strip construction method，The types of utensils are relatively simple，The firing furnace temperature is not high，Easy to break。

Second，Siwa bet365 kentucky bonus code produces pottery tools、Bone tool、Bronze and stone tools，includes ax、Shovel、Knife、cone、needle、Spinning wheel、Whetstone、Net fall、Projectiles, etc.。Although from the perspective of Central Plains bet365 kentucky bonus code，The era of Siwa bet365 kentucky bonus code has clearly belonged to the Bronze Age，But the dominant production tool of the Siwa ethnic group is still pottery、Bone tool、Stone tools, etc.，The types and quantities of bronze tools are relatively scarce。So，The Siwa cultural group is still in the period of the combination of copper and stone and the corresponding production and living conditions to a certain extent。

　Third，Siwa bet365 kentucky bonus code bronzes are mainly weapons and decorations，Many types of weapons，Lots of decorations。Weaponry、Knife、Ge、锞、Spear、Swords, etc.，The decorations have bubbles、Bell、钏、ring、Guan etc.。A large number of bronze vessels were unearthed from the Siwa bet365 kentucky bonus code，But mostly small objects，And the production process is rough，Mostly without decoration，Very few parts have simple embossing patterns on their bodies、Nipple pattern、Geometric patterns, etc.，The overall structure layout is simple，Relatively low technical content。

　Fourth，The popular shape of Siwa bet365 kentucky bonus code tombs is rectangular shaft pit tombs，There are also a small number of cave tombs。The burial style is mainly straight-limb burial，Burial with bent limbs followed，The phenomenon of secondary burial disturbance is relatively common，The coexistence of burial and cremation can be seen in individual tombs。The main direction of the tomb is northwest，A small amount is north-south、North or east。Cutting off the head of the deceased is a popular burial custom in some areas、Palm、Finger、Toes、Pole、The burial custom of mutilation of upper and lower limbs and other body parts。There are two-story platforms and niche facilities in many Siwa bet365 kentucky bonus code tombs，Their function is mainly to place funerary objects and sacrifice people，The second floor platform should also have the function of strengthening the tomb chamber。

　Fifth，Bronze vessels buried in tombs、Bone tool、The phenomenon of jade and other decorations is relatively common，And rich in variety、Various shapes，Reflects the higher aesthetic taste and certain concept of thick burial of the bet365 kentucky bonus code cultural group。Sheep are popular in bet365 kentucky bonus code tombs、Cow、Pig、Customs of bones of horses and other animals，Pig bones account for a certain proportion in early tombs，In the later period, more sheep and cow bones were buried with them，Horse bones are also buried in some tombs。This reflects the farming and animal husbandry production and lifestyle of the bet365 kentucky bonus code ethnic group，And pay equal attention to agriculture and animal husbandry in the early stage，In the later period, more emphasis was placed on animal husbandry.。

　Sixth，Siwa bet365 kentucky bonus code and Kayo bet365 kentucky bonus code、Xindian bet365 kentucky bonus code once coexisted，The duration is roughly the same，Even there are occasional overlaps in spatial distribution，They are likely to have extremely close origins and connections with Qijia bet365 kentucky bonus code。At the same time，Siwa bet365 kentucky bonus code and Liu Family bet365 kentucky bonus code、Pre-Zhou bet365 kentucky bonus code、Zhou Wenhua、Qin bet365 kentucky bonus code also has a certain degree of interaction and blending。From the cultural exchange information reflected in the tomb sites，Although there are exchanges and mutual learning between Siwa bet365 kentucky bonus code and other cultures，But the Siwa ethnic group has a relatively strong self-cultural identity，Siwa ethnic group even if they coexist with other ethnic groups，They will also show their own distinctive funeral customs in their tombs。This aspect contributes to the long-term uniqueness of Siwa bet365 kentucky bonus code，On the other hand, it also prevents it from having a deeper and broader impact on other cultures。

　Seventh，There are many types and quantities of bronze weapons found in the Siwa Cultural Site，This reflects that the ethnic group where the Siwa bet365 kentucky bonus code belongs has a relatively obvious martial bet365 kentucky bonus code。From Funeral、Residence、It seems that there are sacrifices and other situations，There has already been a certain degree of class and rich-poor differentiation within the Siwa community，But overall it is still in a smooth transition stage，There has not yet been a situation of violent social unrest and changes。

　Eighth，The Siwa cultural group once worked hard to expand its sphere of influence to Guanzhong and southeast Longnan，Also interacted with Longdong Pre-Zhou bet365 kentucky bonus code、The early Qin bet365 kentucky bonus code in Longdongnan had a certain degree of interaction。But，With Zhou、The strong rise of Qin’s power and bet365 kentucky bonus code，The main body of Siwa bet365 kentucky bonus code finally ended in Jinghe River、Upper reaches of Weihe River。As an independent bet365 kentucky bonus code，Siwa bet365 kentucky bonus code gradually disappeared in the early Spring and Autumn Period，The main body of Siwa ethnic group is integrated into the Chinese national community，Siwa bet365 kentucky bonus code has gradually integrated into an element of the Chinese cultural system。

Judging from the current archaeological excavation and research results，Siwa bet365 kentucky bonus code extends eastward to Qian at the junction of Shaanxi and Gansu、Wei Intersection Area，The eastern edge of the Tibetan Plateau extending southwest to the western Sichuan Basin，Possible traces of Siwa bet365 kentucky bonus code have even been found in Daxing Town, Ninglang County, Yunnan Province。But，After all, the Siwa cultural relics in the above areas belong to sporadic individuals，It is difficult to form an independent development system，Some of them can only be speculated to be indirectly related to Siwa bet365 kentucky bonus code。

Overall view，The main body of Siwa bet365 kentucky bonus code is located in the Tao River in today’s Gansu Province、Jinghe、Weihe、Western Han River and Bailong River Basin。In the process of long-term production, life and development changes of the ethnic group where Siwa bet365 kentucky bonus code belongs，The following distribution pattern is generally formed: Longzhong area is the central core area，Yilongdong、The two major areas in southeast Longnan serve as transitional peripheral areas，Yiguan Central and Western Region、The northwest Sichuan region serves as two major marginal expansion areas。For that matter，We can basically identify Siwa bet365 kentucky bonus code as a unique local bet365 kentucky bonus code in Gansu in the Bronze Age，It can even be called “Gansu Siwa bet365 kentucky bonus code”。
