The alliance meeting between the Tang court and Tibet was a significant event in the history of relation between the Tang Dynasty and Tibet. The location of the alliance meeting was recorded as the “kavushuvibrang” in the Tibetan historical work, translated as the “Guxing Palace”, referring actually to the “Qingshan Palace” in Wugong county in the western suburbs Chang’an. Moreover, the “Shensanci” in the west of the capital recorded in the alliancemeeting stele in Lasha should be the “Cide Temple”, also called “Qingshan Temple” for being located in the same location as the “Qingshan Palace”. The demarcation site was recorded as the “gonggurmeru” in Tibetan historical works, translated into Chinese as “Moru”,“Konggumeiru” or “Gongbumairu”. The “gonggu” in the name was the “Gonggu Valley” recorded in the memorial stele of The Account of Reestablishing the Ancestral Temple for Gentkeman of Wu’an set in the Song Dynasty, which was situated around the town of Gongmen in the Zhangjia Valley. The “general Valley”, where posthorses were exchanged between two sides, was located around the “Baiqi Castle” west of the town of Gongmen, in honour of the deeds of Baiqi, a wellknown general in the Qin Dynasty. Although some recordings in The Annuals of Tibet didn’t agree with the historical facts of the alliance meeting, they happened to coincide with the status quo of the demarcation line set by the demarcation stele in Chiling.
