This will limit you to 1 in 3 jobs open to foreigners. Which is still very good. See, the main value of a foreign specialist is that he is foreign and supposedly have rare expertise. Second to that, you will most likely to be hired with an idea in mind that you can liaise with overseas customers/specialists/authorities and etc even if your job does not implicitly require that.

Best option is to actively solicit contacts and network a lot. Foreign professionals are a closely knit club here. Industry events are the best if you know nobody here.

Look for job offers in English, job boards of companies with a record hiring foreigners, foreign companies that are new in China, super senior level positions, jobs with PhD. level expertise level, jobs requiring people skills in English "product managers/ field application engineers/ sales or solution engineers"

Websites: 51job, zhaopin, ChinaHR. Look for English language keywords. A post in English almost certainly assumes the company keeps hiring a foreigner an option.
