There must be many considerations to make money, but the key is to have characteristics. In general, only mala Tang is relatively simple in mala Tang restaurants. In those years, Mala Tang was different, and it was very distinctive. The retro style with the theme of memory included not only Mala Tang, but also spicy incense pots, string of dishes and maocai, with many kinds and fresh ingredients. I often come to eat the same food, and I can change to eat several kinds next time. There are many old customers, and business is good, so I will naturally make money.
