Cao Can had a purpose to drink and have fun all day, because the Han Dynasty experienced the hegemony of Chu and Han, and the people lived in dire straits, so they needed to recuperate, reduce the corvee and taxes, and lighten the burden on the people. At that time, Cao Can adopted a laissez-faire policy, drinking and singing with officials, which would narrow the distance between them and be more beneficial to his own policy, so that the Han Dynasty was no longer overwhelmed and gradually became stronger. So Cao Can is called Xianxiang.

Cao Can was the founding hero of the Western Han Dynasty. He used to think that he made the greatest contribution, but Liu Bang only ranked him first, and Xiao He made the first contribution. So there is a gap with Xiao He. Before he died, Xiao He recommended Cao Can as Prime Minister. Although there is a gap between them, Xiao He is still meritocratic, which shows that Cao Can really has the talent to govern the country.

Xiao He didn't see the wrong person, Cao Can is really talented. He believes that the legal system formulated by Xiao He conforms to the national conditions, so he has not changed the laws and regulations, and still follows the previous implementation. Cao Can's selection of subordinate officials is not only based on their eloquence, but also on their practical ability. And informal, subordinates made a little mistake, he will be tolerant. In this way, his men can do things freely, without being cautious and always afraid of making mistakes, and they are more efficient in handling government affairs.

However, people found that Cao Can was particularly fond of drinking, always drinking and having fun, and was indifferent to political affairs. So, I want to persuade him not to drink. But Cao Can understood their intention, and he invited anyone who advised him to drink, so that those who advised him were drunk and didn't even have a chance to speak.

Even officials like to drink and have fun, but Cao Can ignored them. Instead, he indulged in drinking and singing with them, and suddenly distanced himself from officials. From then on, the whole country knows that the relationship between the prime minister and the officials is very harmonious.

When Emperor Hui of Han knew this, he talked to Cao Can and tried to persuade him. However, Cao Can said that he ruled by doing nothing, and rest was more suitable for the Han Dynasty. He can govern the world through Xiao He's laws and regulations. He hoped that Han Huidi could trust him and do whatever he wanted. Although Emperor Hui of Han was dubious, he adopted his suggestion.

Sure enough, Cao Can lived up to expectations. During his tenure as prime minister, the Western Han Dynasty became stronger and stronger, the politics and dynasties were stable, the population increased, and the people lived and worked in peace and contentment, which he highly recognized. Therefore, although Cao Can drank and had fun all day long, he was worthy of the title of the wise man through the ages.
