Generally, people who lose money on light food are untrained, and their own unique recipes do not meet the tastes of consumers. Once they eat, they won't have repeat customers. Nowadays, many light food shops are content-oriented. A store wants to stand out, and good products are the most important thing. Especially in the catering industry, the cleanliness and hygiene requirements of products are strict, and light food catering also needs to ensure the freshness of ingredients in order to make food with good taste. There should be professional and scientific light food training before opening a shop. It has a unique taste and its own brand, so it is difficult to find a good position and lose money.
