the catering industry has the largest number.

The catering industry is the largest, because there are many shopping malls, chain hotels and star-rated hotels in Shanghai, and then there will be many restaurants in the shopping malls.

There is still a great demand for employees in food and beverage outlets, and there are many chain restaurants, each of which needs a team of dozens of people to deliver dishes, chefs and cut and match. Star hotels also have catering. So I think there are the most people engaged in the catering industry in Shanghai.
