Perhaps you should try some spelling variations:
chang won » chang soon, chang ann, chang min
shang kai » shang hai
fan ying » fan xing, ran ying, tan ying
yang jin » yang jun, ying jin, shang jin
won chen » don chen, wong chun, goh chen
yang jie » yang jui, yang xi, yang jun
yang yi » yang xi, yang jui

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((fan ying) OR (yang jin)) chang won chen ((((yang jie) OR (yang di))) OR (yang yi)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: ((fan ying) OR (yang jin)) chang won chen ((((yang jie) OR (yang di))) OR (yang yi)) shang kai ;*.
