The catering industry in Shenzhen has relatively obvious characteristics, that is, the two ends are big and the middle is small. That is to say, the business of high-end restaurants is mostly good, while the business of low-end food stalls and fast food restaurants is generally good and has strong vitality. Generally speaking, the mid-range restaurants have little influence on them. Generally speaking, if they have obvious characteristics and have made a certain popularity, the income is still considerable, otherwise it will be more difficult. Unless you occupy a good location, it is suggested that if you plan to open a restaurant, you'd better have enough characteristics. In addition, you should also make some efforts in publicity and management methods.
