I remember when China wanted to Westernize so desperately that they would hire anyone from the US that had blond hair and blue eyes to teach English or American culture even without a college degree. I think those days are gone....
These are the requirements to teach in China:
"To legally find a job working in China, English teachers require a bachelor's degree and a TEFL certification with a minimum of 120-hours or two years of teaching experience. It is impossible to obtain a Z Visa, which is the only visa English teachers can legitimately work on in China, without these qualifications."
