bet365 withdrawal is one of the most typical representatives of Chinese civilization。China is the first country to raise silkworms and reel bet365 withdrawal，Carbonized bet365 withdrawal and linen fabric fragments dating back about 5,500 years were unearthed from the W164 urn coffin burial in the seventh cultural layer of the Yangshao period site in Qingtai, Xingyang, Henan，bet365 withdrawal fabrics dating back about 4,700 years unearthed from the Yangliangzhu Cultural Site in Qianshan, Zhejiang，All are key archaeological evidence。

The spread of Chinese bet365 withdrawal to the west was as late as the middle and late Warring States Period。Several items unearthed from Bazelek Cemetery in southern Siberia, Russia, dating back to about 2,300 years ago、bet365 withdrawal products with Chu style，Indicates that at this time Chinese bet365 withdrawal had begun to spread westward along the Eurasian steppe to the area where the Scythians lived。About 200 years ago，The Greeks have established multiple trading posts on the northern coast of the Black Sea，A large number of Mediterranean goods are imported into the Scythian region。The Greeks may have been exposed to cultural elements from China at this time。Because a bronze mirror with four mountains pattern from the Warring States Period in China from the 4th century BC was unearthed in the Southern Ural region，It is very close to the Greek activity area on the northern shore of the Black Sea-Caspian Sea，The possibility of importing Chinese bet365 withdrawal cannot be ruled out。But because of the Eurasian steppe、The trade routes in northern Central Asia are in the hands of nomadic peoples such as Scythia，And restrictions on navigation conditions in the Indian Ocean，Whether it is Herodotus’s time，It was still the Hellenistic era started by Alexander，Neither the Prairie bet365 withdrawal Road nor the sea routes connecting Chinese and European civilizations have been truly formed。

From the second half of the 1st century BC，The term "Seres" began to appear frequently in the context of Western geography，The connotation is closely connected with the East and bet365 withdrawal。The earlier systematic discussion of it comes from the ancient Greek geographer and historian Strabo。

Recorded in Strabo's "Selected Classical Works"，“The terrain of India is diamond-shaped，At its northern end is the Caucasus Mountains，Stretching from Asia to its easternmost edge，This mountain range separates the Serb people in the north、The Scythians and Serians were separated from the Indians to the south"。According to Strabo's "Geography"，“Selika (fabric of the Seris) is a textile made of ‘bisus’；Bisus is spun from some kind of skin”。He believes that the characteristic fabrics of the Seris people come from "a certain kind of skin"。The poet Virgil, who lived slightly earlier than Strabo, wrote in "Pastoral"，“The Sirians gathered very fine wool from their leaves”。Describes the second half of the 1st century BC，The Western understanding of the origin of Chinese bet365 withdrawal is not yet unified。"Geography" also mentions the "wool-growing tree" in India，This is obviously a reference to the Indian tree cotton already used by the Greeks in the time of Alexander。The speculations of Western writers contemporaneous with Strabo and later on the origin of Chinese bet365 withdrawal seem to be influenced by Indian tree cotton。

Strabo’s discussion of “Serys” and bet365 withdrawal，Represents the West’s new understanding of the region east of India after Hellenism，This is directly related to Emperor Wu of the Han Dynasty sending Zhang Qian as an envoy to the Western Regions。Zhang Qian’s mission to the Western Regions，Carry a lot of bet365 withdrawal，Xiang Dawan、Kangju、Da Yueshi、Daxia、RIP、Body poison、奄草、Tiaozhi and other countries sent deputy envoys。Although blocked by the road，Message delay，But the influence from the Eastern Han Empire and bet365 withdrawal has spread to the West，After several changes, it appeared in the context of Western natural history and geography in the second half of the 1st century BC。Zhang Qian not only had the merit of "emptying out the Western Regions"，It should be better known as the East-West bet365 withdrawal Road，This is a middle road different from the Black Sea-Caspian Sea northern coast Eurasian steppe and the southern maritime route。Oriental silks soon inspired a "luxurious style" in Rome。

From mid to late 1st century，The geographical position of West to Seris、The appearance and customs of the Seris people，And its specialty "wool that grows on trees" and fabric (bet365 withdrawal) are further described。Meila's "Local Chronicle" in the mid-1st century，“Starting from the East，The first people people meet in Asia are the Indian nation、Serys and Scythians。The Seris live in the center near the east coast，The Indians and Scythians live on the edge”。Mehra earlier presumed that the central location east of India near the East China Sea was the place where the Seris people lived，This is consistent with the location of the territory of the Han Empire at that time。“The gap between the two mountains (Tabis and Taulu mountains) is inhabited by the Seris people。The Seris people are a nation full of justice，Famous for its peculiar trading methods，This method is to place the product in a remote place，The buyer came to pick up the goods when they were not present。"The "Sairis" described by Mela as living in the gaps between the mountains should be the ethnic group living in the western frontier of today's China。

Pliny the Elder, who was a little later than Mela, made new additions，Written in his book "Natural History"，"(Serys) are famous for the wool produced in their forests。They sprayed water on the trees to wash away the white fuzz on the leaves，Then their wives will complete the two processes of spinning and weaving。Because there are people in remote areas completing such complicated work，Only Roman ladies can wear transparent clothes and show off in public。Sailis people have a gentle personality，But they avoid interacting with people like savages，But just wait for the merchant to do business with him”。Classical writers in the 1st century all adopted the description of cyris as "wool that grows on trees"，Suggests that the secrets of Chinese bet365 withdrawal making were kept secret for the first two hundred years of the bet365 withdrawal Road。Trading method that avoids people，Perhaps one of the effective ways to protect the secret of bet365 withdrawal。

Pliny the Elder's "Natural History" also records the appearance of part of the Seris people，(During the reign of Claudius，i.e. AD 41-54，The embassy from Sri Lanka told the Romans) that the Seris had been seen in areas beyond Mount Hermody，And maintained trade with them。The father of the head of the mission, Lasias, once visited the country of Seris；The Seris welcome travelers，Their stature is larger than that of ordinary people，With red hair，Blue eyes，Rough voice，Don’t talk to outsiders easily。The Hermody Mountains mentioned by the Sri Lankan mission may be the Himalayas，The "Sairis" they saw may be the nomadic group living on the Qinghai-Tibet Plateau in China at that time，Not the same group of people as described by Meira，And the mission did not mention that there was bet365 withdrawal in their deal。

"Natural History" records，The Romans spent huge sums of money every year to purchase goods from Arabia、Luxury products of India and Siris，“Based on the lowest estimate，India、Serys and Arabia take 100,000,000 sesterces every year from this empire (Rome): this is what luxuries and our women cost us”。bet365 withdrawal should account for a high proportion，This is also consistent with Tacitus's "Annals" recording that bet365 withdrawal caused extravagance。

What is interesting is that Pliny the Elder recorded that there were larvae of a local silkworm moth (silkworm) in Assyria (now northern Iraq)，“Like a spider weaving a web，These things can be used to make haute couture skirts worn by women，This substance is called bet365 withdrawal”。This is obviously a wild bet365 withdrawal textile technology，The Romans didn’t know that Chinese bet365 withdrawal was produced from domestic silkworms，Not comparing the two，It also shows that the appearance and quality of Chinese bet365 withdrawal and local "wild bet365 withdrawal" are very different。Pliny the Elder recorded that the women of Kos Island used "wild bet365 withdrawal" to weave clothes, which was first seen in Aristotle's "Animala"，This indicates that it was no later than the middle of the 4th century BC，The tradition of using wild bet365 withdrawal to make clothes already exists in the Mediterranean region。Research in recent years shows that，Some of the bet365 withdrawal fabrics unearthed in the ancient city of Palmyra from the 1st to 2nd centuries are made of wild bet365 withdrawal，It cannot be ruled out that it is the "Assyrian bet365 withdrawal" mentioned by Pliny the Elder，Or "Kos bet365 withdrawal" in Aristotle's account。

An anonymous work "The Voyage of Eritrea" at the end of the 1st century recorded the navigation route from India eastward to China，Including a city called Qinni，The silks there are shipped inland to Bactria and India。This is the earliest description of China’s inland cities in Western physical geography，It also indicates that some Chinese bet365 withdrawal has been transported to the West by sea route。

From the second half of the 1st century BC to the end of the 1st century AD，Serys and Oriental bet365 withdrawal by Western Poets、Widely praised by playwrights and historians。97 AD，Ban Chao sent Gan Ying as envoy to Da Qin (Rome)，Gan Ying's "Guitiaozhi"，Looking at the ocean and returning with a sigh。Based on the division between Parthia and the Roman Empire at that time，Gan Ying may not have been able to cross the Euphrates，The sea may be the Persian Gulf。Just like Zhang Qian sent his deputy envoys to visit Western countries 200 years ago，The Han envoys’ journey to the west will surely spark a new wave of Eastern exploration。

2nd century，Ptolemy is based on a man who owned a caravan between Syria and China、Information provided by merchants engaged in bet365 withdrawal trade，Measuring the distance from the Euphrates River in Syria to the city of Serra, the capital of the country of Seris，The "Stone Castle" is less than halfway along the route，It is 7 months away from the city of Sera。The "Stone Castle" may be the ruins of Stone City in Taxkorgan, Xinjiang，Saira may be Xi'an。Ptolemy also speculated on the latitude and longitude coordinates of some cities in Serris，The location is not yet clear。Pausanias, a contemporary of Ptolemy, described in the Hellenica that the threads of Seris were not from bark，It comes from an insect that spins bet365 withdrawal。It is a pity that this breakthrough understanding was not inherited by subsequent natural geographers。

　166 AD，The envoy sent by the Roman Emperor Anton by sea arrived in the Han Dynasty via Rinan，This may be one bet365 withdrawal most important breakthroughs in classical natural geography，Unfortunately, this messenger failed to leave any records。

bet365 withdrawal end of the 2nd century to the end of the 4th century，Rome、China’s two great empires each experienced turmoil and disaster，The Sasanian Persian Empire emerged in the first half of the 3rd century，The West’s enthusiasm for exploring the East is gradually fading。The crystallization of ancient Eastern wisdom transmitted to the west, represented by Seris and "wool growing on trees", serves as the heritage of classical natural history，Continue to wander among the writing styles of Western writers。
