I think the main reasons why he can open so many hot pot restaurants are: firstly, he is very nice; secondly, he has a certain business sense; thirdly, as a star, his audience relationship is quite good.

Specifically,

1. First of all, it can be seen that he is very kind and interesting. He has been watching running men since that time in 2115-16. In the first two seasons, he especially liked his funny appearance in the game, and his laziness made people feel particularly comfortable. There is also Ceng Xiaoxian in ipartment, which he filmed earlier, and this role is deeply imprinted on us.

2. With a business mind, he knows what is easier to make money in this era. For example, in the catering industry, many stars now open restaurants, but some stars shut them down. Restaurants not only need star effect, but also have their own characteristics to open for a long time. He must have chosen to open a hot pot restaurant after long-term research and careful thinking.

3. It is not excluded that besides the above two points, there are fans who like him to hold his venue, or some ordinary people are curious to see what his hot pot restaurant tastes like.

As far as the above three points are concerned, it's not surprising if his business can make a lot of money. It's possible for an ordinary citizen to make money by opening a hot pot restaurant. As a star, he has more advantages and is certainly easier to make money.

The above is my personal opinion. I hope to help you. Thank you!
