After Ma Xisheng took the reins of the state, he began to run into conflicts with Gao Yu, and he was also suspicious of Gao due to the prior seeds of suspicion sewn by Emperor Zhuangzong and Gao Jixing (who, while alive, had publicly stated that he wanted to enter into a blood brotherhood with Gao because he believed that Gao would become Chu's ruler). In 929, with Ma Xisheng repeatedly requesting it, Ma Yin ordered Gao into retirement. Gao, in frustration, stated, "I am going to build a mansion in the hills to the west, for retirement. The pony [(employing a similar double entendre as Xu did)] has grown up and can bite now." Ma Xisheng heard the remark and became angry — so angry that he falsely announced that Gao had committed treason, and he slaughtered Gao and his family, without first informing Ma Yin. When Ma Yin heard this, he cried bitterly, but did not punish Ma Xisheng.
