Perhaps you should try some spelling variations:
chang yun » chong yun, chang hsun, chae yun
lang yan » wang yan, wang yang, zhang yan
yang yun » yang jun, tang yun, yang yue
yan yuan » yan guan, fang yuan, nan yan
yang jui » yang judy, yang di, yang yi
kang hai » dang hai, kang han, shang hai
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: lang yan ((((chang yun) OR (yang yun))) OR (yan yuan)) tan ((yang xi) OR (yang jui)) kang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((chang yun) or (yang yun))) or (yan yuan)) tan ((yang xi) OR (yang jui)) kang hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((chang yun) or (yang yun))) or (yan yuan)) tan ((yang xi) OR (yang jui)) kang hai ;*.
