Perhaps you should try some spelling variations:
chang hsun » chang ch'un, chung hsuan, chang su
wang yong » wang yang, wang hyoung, wang yan
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang di, yang yi
gang hai » dang hai, eang hay, gang hu
yan yun » yan yuan, yang yun, yan kun
yang xi » yang di, yang yi

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: wang yong ((yan yun) OR (chang hsun)) gain ((yang jui) OR (yang xi)) ((gang hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yan yun) or (chang hsun)) gain ((yang jui) or (yang xi)) ((gang hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yan yun) or (chang hsun)) gain ((yang jui) or (yang xi)) ((gang hai) OR (shang hai)) ;*.
