China Work permit requirements

Hi Im Margaret, a Canadian citizen currently living in Canada.

I have a firm job offer from a Chinese company. I got my degree 25 years ago but I lost my diploma (long story). Can the company get a work permit for me in China?

I'm an I.T. professional with 20 years experience in Information Technology. I also have taken IT courses (with certificates) over the years. Would this be sufficient. If not, what are my options.
