Beijing includes food, accommodation and work! thank you

I don't know if it's a boy or a girl. When I first came to Beijing, many people would like to find a job with food and shelter. When I came to Beijing, I worked in a business hall. I can try network maintenance, such as Yihai International, Southland Nature and Halla Mountain, which are basically recruited all the year round. There is really not much work in Beijing to manage food and accommodation. If you are a girl, you can work as a cashier or a clerk, mainly in the service industry. Because of the work schedule in the service industry, the staff in this industry must stay in the company to eat and live.
