Xiang Yu, the adviser of Qin State, suggested killing Liu Bang to avoid future troubles, but Xiang Yu looked down on Liu Bang. He was just the director of Surabaya Pavilion and would certainly deal with it in the future. Later, Xiang Yu thought that Liu Bang would be controlled by the three commanders of Qin Dynasty, and Liu Bangming took advantage of the plank road to secretly capture Cheng Peng, the capital of Xiang Yu. Although Xiang Yu saved the day and defeated Liu Bang, he still didn't realize that Liu Bang was his biggest enemy and went on doing it.

2. Wu Wang.

During the Spring and Autumn Period and the Warring States Period, the king of Wu did not listen to Wu Zixu's suggestion of destroying the country first and then reunifying the whole country, and he reused the traitor Taizai. In the end, Wu Zixu was sentenced to death without listening to his plan, and was finally destroyed by Gou Jian when his national strength was empty.

3. Masu.

Ma Su Lost Street Pavilion: At that time, Ma Su just ignored Wang Ping's proposal to camp at the foot of the mountain. He was conceited and familiar with the art of war. Zhuge Liang used it for his own use and camped on the mountain in an attempt to use the terrain to repel the enemy. However, Wang Ping is a veteran, and all he thinks about are some practical issues such as camping in the mountains, cutting off food, grass and water. However, Masu wouldn't listen. As a result, Wei Jun ran out of water, lost his street pavilion, and was finally beheaded by Zhuge Liang.
