Why is "Qiān Zhī Fú" trending?

Wikipedia Overview

Syamapura Kingdom or Bàn Zhī Bá (半支跋), or Gàn Zhī Fú (干支弗), was a medieval polity located in the Southwest Sea region, with its political center at Si Thep in the Pasak Basin of central Thailand. To the north, it adjoined the territory of Duō Mó Cháng (多摩萇). Historical and archaeological evidence indicates that Qiān Zhī Fú was originally established as a colony by settlers from southern India, maintaining enduring cultural, economic, and political ties with the Indian subcontinent. By the mid-seventh century, during the reign of Emperor Gaozong of the Tang dynasty, Qiān Zhī Fú functioned as an independent state and engaged in tributary relations with the Chinese imperial court. Contemporary Chinese sources record that the polity maintained a standing military of approximately 20,000 elite soldiers, although it notably lacked cavalry. Accounts of the region's geography indicate that the territory could be traversed in roughly one month from east to west and twenty-five days from south to north.
