Hi Karnal, since I received you private message in bitsharestalk.org, I have forwarded this survey to a few chat groups of Chinese communities. A few of them just confirmed that they have finished the survey. Noting that many of them are living abroad, maybe that's why you mentioned that only 4 were from China. I can name at least 10 of them.
Indeed, English is the main obstacle.
How far away from your target(100 if I remember correctly)?
