Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
shang kai » shang hai
wing ian » wing tan, twinn ian, wing sun
yang lin » wang lin, yang li, yang liang
yang jin » yang jie, yang jun, ying jin
han hua » tan hua, wang hua, tuan hua
hong » long

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing ian) OR (hong tan)) ((han hua) OR (tuan china)) gain ((yang lin) OR (yang jin)) shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing ian) or (hong tan)) ((han hua) or (tuan china)) gain ((yang lin) OR (yang jin)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing ian) or (hong tan)) ((han hua) or (tuan china)) gain ((yang lin) OR (yang jin)) shang kai ;*.
