As the supreme king, why did Sima Yao laugh himself to death?

Because Sima Yao once joked about his beloved princess after drinking, and then he went to find a young woman to be his concubine. As a result, this concubine killed her heart. After Sima Yao fell asleep, he smothered him with a pillow.

Sima Yao is said to have been born at dawn, so his writing is bright. He was the third son of Sima Yu, and Jian Wendi insisted that Sima Yu inherit the throne, because Huan Wen ruled the whole dynasty at that time. Huan Wen thought that Sima Yi would give him the throne. Unexpectedly, Sima Yi gave the throne to his son Sima Yao and made him an assistant minister, thus pushing Sima Yao to the throne of the emperor.

Sima Yao was only twelve years old when he became king. In July of the following year, Minister of State Huan died of illness. In 376 AD, Sima Yao officially proclaimed himself emperor, and he appointed Xie An as assistant minister. Xie's brother and nephew Xie Xuan are both talented military strategists. They were also loyal to Sima Yao and played an important role in the stability of Sima Yao's throne.

But Sima Yao doesn't care about state affairs. He doesn't look like an emperor. He advocates the philosophy of Huang Lao and leads an easy life every day. At the same time, he began to doubt his uncle Xie An and nephew, fearing that they would affect his position, so he asked his brother Sima Daozi to do bad things. Sima Daozi is greedy and cunning. He colluded with the villains and opposed Uncle Xie An everywhere. Later, Xie An was excluded by them and died soon.

One day, Sima Yao was drinking with his favorite concubine, Zhang Guiren, and Sima Yao was drunk. He joked with Zhang Guiren that Zhang Guiren was old and wanted to put her in limbo, but because two concubines were in limbo a few days ago, Zhang Guiren was afraid of losing her favor and killed Sima Yao after listening to it.
