Has anyone joined Mengziyuan to cross the bridge rice noodles, and what is the profit?

After working in Mengziyuan for several years, I moved several stores one after another. As far as joining is concerned, joining is not recommended. First of all, all the materials and edible materials must be provided to you by Mengzi source, and the price is not negotiable. And the quality control of Mengziyuan is very weak. The ingredients sent are often changed, the brands are different, the tastes are different, and the seasonings with the same taste are different. In the past, the two houses in Beijing had all closed, and the one in the north didn't make money. It is hard to find places in the south, and employees are treated with benefits. No employee wants to develop here. Can this shop get better? It's even better to make your own rice noodles. Find a chef to try it. Why spend money on some bad technology?
