Chengdu has the Tang "Pingnan Barbarian Monument", which was erected by Zhang Jingzhong, deputy ambassador of Jiannan Jiedu in the nineteenth year of the new century. At that time, the great chieftain of the Southern Manchus, Shi Yangsheng of The Southern Manchu Prefecture, was a border trouble, and the Ming Emperor sent the Internal Attendant Gao Shouxin to solicit consolation for the Southern Province, and pulled out its nine cities. This matter is not recorded in the new and old Book of Tang and the Wild History. Emperor Suzong took Yu Chao'en as the envoy to watch the army, and Emperor Xianzong used Tutu Chengxuan as an envoy, and the deliberators ridiculed him for taking the middle man as the main military leader, not knowing that the Ming Emperor used trustworthiness and covered with Yi Qizhiye. Pei Guangting and Xiao Songshi are phases, and those who are not responsible. Yang's Miao descendants, still lian Sheng zi yun.
The translation is: There is a Tang Dynasty "Pingnan Barbarian Stele" in Chengdu, which was established by Zhang Jingzhongli, deputy ambassador of Jiannan Jiedu in the nineteenth year of Tang Xuanzong's kaiyuan (731). At that time, the Great Chieftain of the Southern Manchus, Shi Yangsheng, invaded the border, and Emperor Tang Ming sent The Constant Attendant Gao Shou to trust the Southern Province to invite and dispose of the envoys to go on a crusade and capture nine cities. This is not recorded in the New Book of Tang, the Old Book of Tang, and other wild histories. Emperor Suzong of Tang appointed Yu Chao'en as the envoy to guan jun rong, and Tang Xianzong appointed Tutu Chengcui as an envoy, and the commentators ridiculed them for using eunuchs to control military power, but did not know that Emperor Tang Ming had already set a precedent. Although Pei Guangting and Xiao Song were doing chancellors at that time, there was no need to be blamed. The descendants of the Yang clan, until now, still have the word "Sheng" connected to their names!
Comments: No matter how hard people who write history, they will inevitably have omissions and mistakes, so future generations cannot read books.
