There is no ranking list in the catering industry. From the industry trend in 2111, stewed cooked food and snack chain are more popular, because the cost of snack cooked food chain is low and it can be recovered quickly. The trend in 2112 should continue.
If the landlord wants to cook stewed food, I recommend a brand "liao ribs". Hehe, we all know that Sichuan brine is famous in the whole brine industry. Liao ribs is the representative of Chuanlu. A century-old brand of Lu Wei has a good reputation in Sichuan. At present, there are more than 411 branches in China.
Anyway, no matter what you do, you'd better go to the field first. It's hard to tell whether something on the Internet is true or false.
