How much does it cost to join the beef bone buffet hotpot?

What kind of food are you talking about? Each person charges one person, and a catty of bones is free. I used to eat Wang Xiangwang in my hometown. It's delicious and affordable. As far as I know, it seems to be about 30 thousand. Still have to call yourself or check online. There are quite a few brands that do beef bone self-help. I suggest you make a field trip and have a taste.
