Examples of celebrities who practice are as follows:

1. During the Warring States Period, Zhao Kuo, the son of Zhao Hao, a famous general of Zhao State, was proficient in the art of war when he was a child and was good at talking about soldiers. Even his father couldn't beat him. Later, the king of Qin among the Zhao kings did the opposite and asked him to replace Lian Po as the general of Zhao.

Zhao Kuo is a person who lacks actual combat experience and only understands the art of war. When he arrived in Changping, he reversed Lian Po's actions, changed the lieutenant, and changed the military system, which made the whole army lose morality and demoralize.

He changed Lian Po's strategic defense and actively planned a strategic offensive in an attempt to win in one fell swoop and recapture Shangdang. In the Battle of Changping, Zhao Kuo only knew how to fight according to the art of war, and did not know how to deal with it flexibly. After that, he was shot dead by the Qin army, and all 400,000 of his men were captured.

The state of Zhao perished. Although it is common for soldiers to win or lose, the war guided by the knowledge summed up in practice has a great chance of victory.
