i 've never traveled before and want to travel to china what advices do u give to me?

Don't be nervous. It's not too difficult for you to travel in China. Generally speaking, it's safe to travel across China. I don't advise you to bring much cash with you. It's not safe and you should be careful with the pickpockets. Also you should keep your passports and other important documents safe.

The easiest job is to teach English. Of course you can try to find other kinds of jobs. Comparatively, your income can support your living in PRC very well. And there are many western restaurants in major cities. And you can try Chinese food. They are delicious.
