The cause of Mianchi meeting was that Qin and Zhao met in Mianchi. After that, the prince of Zhao drummed for the king of Qin, and Lin Xiangru forced the king of Qin to beat him with his life. The result is to save Zhao's face.

The whole story of Mianchi Conference: Mianchi Conference took place in 279 BC. In the twenty-eighth year of Qin Zhaoxiang, Zhao Xiang, the king of Qin, wanted to concentrate on attacking Chu. In order to get rid of worries, he took the initiative to make friends with Zhao and invited Zhao Huiwen to work in the pool.

The king of Qin sent messengers to tell the king of Zhao that he would meet him at Mianchi. The prince of Zhao was afraid, but he didn't dare not go. Lin Xiangru accompanied the prince of Zhao to Mianchi. When the king of Zhao was forced to play the harp, he argued for equality with Zhao Ping, forcing the king of Qin to strike. Later, Qin asked Zhao to beat the king in fifteen cities, but he refused to give in, saying that he used Xianyang, the capital, to beat Zhao for his birthday, so that Wang Gu had no income. Lin Xiangru tactfully protected Zhao's safety without being humiliated, which was called "Mianchi Meeting" in history.
