You can look for it on your local talent network. In my personal experience, you'd better go to the street to find fast food restaurants like Auntie Dumplings 7+7 KFC and McDonald's. Need to recruit people. But catering needs a health certificate. In addition, Suning Appliance and Gome also seem to need summer jobs. If you are eloquent, you can also get a resume and find some telephone sales representatives and other work exercises in the talent market. If you want food and shelter, you must go to a restaurant. Generally, restaurants have to get food and accommodation.
