Yu Yan is one of the four Anxi towns in the Tang Dynasty，Play an important role in the process of operating the Western Regions of the Tang Dynasty，and the central power can be implemented by the following，It is inseparable from the guarantee of the military and political system。For this，Meng Xianshi bet365 Play online games has made "Yu Xun: Evolution from Zhenyu to Military Town", "Discussion on the Museum of Renmin University of China with the Museum of Renmin University of China"，Prove that the Tang Dynasty started after the first year of longevity (692) after the Tang Dynasty was stationed in the four towns，The defenders in the town of Yuyu and the four town of Anxi, as the new military town system, later settled，Controlled and dominated the system of the original Visha Dudu Mansion and Anxi Dufu Mansion，Change the military pattern of the Western Regions，Make military town into a development direction。

Stable rule in any region，Can't be separated from powerful military jurisdiction，It is also inseparable from orderly economic governance。So，Under the military town system，How can the economic activities in the Tang Dynasty in the area of ​​the Tang Dynasty carried out in an orderly manner? Scholars found a lot of answers from the records of people's blogs and Tian Duke。such as tax system，The guardian of the town of Yu Xun is taxing locally，It does not rely on the king's king system，Instead, it can be charged directly to the local people。Liu Zifan's "The Sure in the Township of the Town and the Local Society"，By analyzing GXW0062、GXW0065 and other documents，I found the basis for taxation，That is, the defenders in the town of the town have effectively mastered the number of local people and the statistics of the male Ding。Ding Jun's "Preliminary Examination of the Tax Taxation System bet365 live casino games in the Town" further confirmed，The taxation system within the guards in the town of Yuyu is very tight and perfect，Correspondence on management，Clear task，Complicated transactions，to assume the function of independent military supply。Through Sun Bingzheng's "Research on the Taxation System in the Taxation Region after the Anshi Rebellion"，We know，After the Anshi Rebellion，Even the connection between the guards and the central government is interrupted，Unable to obtain central supply，But with the strict system of "National -State -Township -Village"，Relying on local materials support，Still insisted on the period of Tubo occupation。

Another example，As a kind of tax system，The "Tax Food" system is missing in the handed down classics，Now because of the human blog and Tian Wenhua,。Ding Jun passed GXW0166R "Tang Jie Xie Town as the 17th year of Dali Town should manage the grain and use food breaks, etc."，Discussion on the object issued by the public grains in the area、Standard，Think that the object of grain is the official，The standard is one stone millet (or wheat per person per person per month、Qingmai)。Study on related issues，More concentrated in Qing Zhaorong in 2022、The series of articles jointly completed by Rongxinjiang "The Examination of Tax and Food Related Document Related Disciplinary Discipline", "During the Earth of Hetian During the Examination of Tax and Related Books", "Tax Food" system in the Tang bet365 Play online games Dynasty 》，demonstrated the front of Anshi，The tax collection of Yu Xun has begun to take shape，The primary use is to replenish food to the people by recruiting food from the people;，Extracting due to the burden of the people，Tax and grain owe exacerbation，It will also use measures to be discounted by money for collection。

In addition to tax，Water Conservancy Yingtian、Folk contract is also an important face for economic development。Liu Zifan's "Jie Xie Ying Tian and Water Conservancy -Research on Water Water Water in Hetian Zuo"，"Under the local special military and political system，"Under the local special military and political system，Reflected that the power of the guards of the town of the town participated in the management of civil affairs to a certain extent "。Discussion on the "Discussion on the Hosian Museum of Renmin University of China and related issues and related issues" uses more than 10 pieces of GXW0038 in the 阗 Contract document，Prove that Yu Qi and Gaochang Chief、The extension of the content of Xizhou Equipment，and reveals its own characteristics，is the improvement and harshness of the preventive clause。

"Money" and "帛" as an indispensable element for economic activities，The attention of scholars。Duan Qing、Li Jianqiang "Money and Symposium -Three Masters of the Museum of Renmin University of China — Analysis of Chinese Bilingual Books"，Bibo "The" Guan "in the Tang Dynasty in the Western Regions", "A fabric of the ancient Yuyu -White bet365 live casino games 氎", etc.，Although the specific research objects are different，But in terms of methods, they are discussed in conjunction with Han literature with Yu Ying's documents。

Hetian area is the western end of the Western Region's Chinese document，This not only reflects the cultural integration of the Tang Dynasty in the area of ​​the Tang Dynasty，It also proves the strong vitality and appeal of Han culture。People Bo and Tian Shuo，Most of them are seriously broken，But still retains rich cultural information。Rong Xinjiang "" Lanting Preface "in the Western Regions", "Wang Xizhi" Shangshang Huang Qi Tie "in the Western Regions，Pay attention to the situation of the two calligraphy posts that spread to the status of the area，and use this as the entry point，Examine the spread of the Central Plains Culture in the Western Regions; Chen Lifang's "Tong Meng Education in the Tang Dynasty in the Tang Dynasty — Centers for the Museum of Renmin University of China"，Then turn the perspective to children’s enlightenment education，Revealing the role of Han culture in it; while Liu Zifan's "The Tang Dynasty Letter of the Tang Dynasty, the Test of the Tibetan of the Renmin University of China"，Several letters with direct sealing leather through GXW0199，Back to the Tang Dynasty letters and sealing methods; Duan Zhenzi's "Chinese manuscript lies in 阗 — centered on the Chinese Wenwen Document of the Western Region of Renmin University of China"，Showing Han culture in the scale of the propagation。

People Bohe and Tian bet365 live casino games Dai are collected，But the preliminary judgment of Jingrong Xinjiang，In terms of content, it has a certain connection with the Chinese National Library and the Tian Daiwen，At the same time with Stanin、Peter Rovesky、Swenhe Ding and other income English、Russia、Hetian unearthed in Hetian in Swedish collected Chinese documents related to each other。These more than 300 Hetian documents at home and abroad，Has been compiled and published by Rongxinjiang in "The Tang Dynasty in the Tang Dynasty in Hetian"; at the same time，The finishing work of Renfang and Tian Shuo is also conducting in an orderly manner。According to the existing materials，Meng Xianshi has outlined it during the period of 阗 阗、Four Town Early Period、Late Town、Different historical appearances presented by "Hou'an Shi Rebellion"。I believe that with the emergence of more historical information，These documents will play more important characters in the study of history，The history of Yu Xun will also be more three -dimensional、Full。
