Clever application of Zhuge Liang's three tricks

1: Send people everywhere to spread the news that Sister Sun Quan and Liu Bei are getting married (especially to tell Joe that he is Zhou Yu's father-in-law and tell Sun Quan's mother through him).

2. Let Zhao Yun tell Liu Bei that when Sun Quan and Zhou Yu detained Liu Bei in disguise, Cao Cao would come to Jingzhou to urge Liu Bei to go back.

3. Let Liu Bei tell Mrs. Sun the truth when Wu Pai people recover Liu Bei, and let Mrs. Sun (the one who married Liu Bei) come forward to stop it.

In fact, it is debatable whether Zhuge Liang left any tricks in real history.

Most historians think that The Romance of the Three Kingdoms is a novel after all, and it is not credible. But in the official history, according to Zhuge Liang's life records, he has not been found to have a secret kit.
