Liu Bangdang, the curator of Surabaya Pavilion, always drinks on credit, but the store never pays him back for free, mainly because the store wants to accommodate Liu Bang, so as to attract more guests through his extensive brothers, and at the same time, he can rely on Liu Bang's identity to let Liu Bang protect his business.

Liu Bang was born in a very ordinary peasant family, but he didn't like farming very much. He always likes to drink with his friends, but he always goes to two stores to drink. Every time he invites Liu Bang to dinner, he pays the bill. However, the two pubs did not ask Liu Bang for debts, but at the end of the year, they wrote off some previous credits. Mainly because Liu Bang has a wide range of friends, the two pubs want to please Liu Bang in this way and let him attract more guests for his pub, so that the business of the pub can become very good.

At the same time, Liu bang is also a person with status in that place, and ordinary people will not provoke him. In a very complicated place like a pub, there are always people who get drunk and then make trouble. Therefore, with Liu Bang's identity to protect them, it is equivalent to finding an amulet for their pub, and no one dares to make trouble in their pub. The most important thing is that Liu Bang's own salary is simply not enough, so he is penniless, and even if he wants to pay, he won't want money. In this case, he might as well bend the rules.

Unlike Liu Bang, he doesn't want to spend too much effort to ask for accounts, and then please Liu Bang at the same time, so that he can attract more guests for himself and keep his daily business from being disturbed by some drunkards.
