Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
shang kai » shang hai
yang jin » yang jie, yang jun, ying jin
tan yang » dan yang, tan ying, tan yong
wing ian » wing tan, wing sun
chang ha » chang mae
han hua » tan hua, wang hua, tuan hua

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 (twinn ian)) ((han hua) OR (than china)) tan yang jin ((shang kai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing ian) OR (twinn ian)) ((han hua) or (than china)) tan yang jin ((shang kai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing ian) OR (twinn ian)) ((han hua) or (than china)) tan yang jin ((shang kai) or (chang ha)) ;*.
