Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
shang kai » shang hai
wing ian » wing tan, twinn ian, wing sun
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
chang ha » chang mae
han hua » tan 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 ((((han hua) OR (wang 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 ((((han hua) OR (wang hua))) or (than china)) tan yang jin ((shang kai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ian ((((han hua) OR (wang hua))) or (than china)) tan yang jin ((shang kai) or (chang ha)) ;*.
