Many industries have peak season and off-season. Even our daily necessities change with the seasons, such as clothing. Because of the different seasons, clothing also has different changes in the market. Because of this, no clothing factory makes clothing in one season. If it is summer, then winter clothes will naturally be hard to sell. Although there are anti-season clothes now, most people think they are outdated clothes. Even if there are some preferential prices, many people will not choose to buy them.

The same is true for the catering industry. In general, the business of tea shops in summer will be better than that in winter. For example, the business of cake shops in winter is better than that in summer. However, some catering enterprises, especially the western-style fast food industry, are full in all seasons, just look at the people who are full every day in McDonald's and KFC.
