Don't be overwhelmed

Imagine telling a Chinese citizen to fly to the United States to "walk around and stop in" at schools looking for a job.
The land mass of China and the U.S. is approximately the same and China has four times as many residents and countless more 'schools'.
I've been working in China for ten years and speak Mandarin. If I was considering a job in, say, Shanghai, I could spend months visiting different universities and private schools. I would certainly be overwhelmed.
The expense and time commitment alone makes this an impossibility. In the real world, research is done on-line and communication occurs on skype and in emails.
Too often foreigners in China believe that their idiosyncratic personal experiences in China is generally applicable. Communicating your experiences is valid and perhaps valuable, but giving advice is assuming responsibility in a situation with which you have limited knowledge, of both China and the person you have chosen to advise.
