Mawei Station mutiny
The Maweiyi Mutiny was a mutiny that took place at Maweiyi on June 14 ,756, which led to prime minister Yang Guozhong and his cousin Yang Yuhuan were killed.
Escape to the west
After the fall of Tong Pass in the An Lushan Rebellion, Emperor Xuanzong fled Chang'an with members of his court, including his favourite concubine Yang Guifei, Crown Prince Li Heng, Prime Minister Yang Guozhong, General Commander of the Imperial "Longwu Army" Chen Xuanli and his closest officials.
Meeting of Golden Turtles
When they arrived at Maweiyi, Yang Guozhong secretly held a meeting of Golden Turtles, forming a makeshift rectangle with their wagons in a secluded clearing and using the rear curtains to conceal themselves as they faced one another. They discussed their predicament, recognizing that Guozhong had dramatically lost favour with the Emperor for his abject failures. Fangjin alerted Guozhong that the soldiers escorting them were famished, exhausted, and brimming with rage, and that they needed a scapegoat to divert their wrath. Yang Guozhong put the blame on Bian Lingcheng, and said that he had sent him to stay in Chang'an. Yang Guifei's sisters, the Lady of Han (Lady of Korea) and the Lady of Guo (Lady of Guo), assured him that once they arrived in Shu, where they had local support, they would be able to reassert control over the Emperor. At the same time, the members of the Golden Turtles were surprised that Gao Lishi was often absent from the regular meetings recently. After discussing the progress of the war, Yang Guozhong once again put the responsibility on Geshu Han, Wang Zhongsi and Crown Prince Li Heng. He decided to thoroughly investigate the prince's party after arriving at Shu.
