Perhaps you should try some spelling variations:
kian wing » kian ming, kian wie
yang dong » yan cong, yang jing, yang xuedong
yang yang » wang yang, wang yan
jeng dong » eng hong, zeng doug
lang yan » wang yan, wang yang, zhang yan
dong di » dong sin
wing yi » ming yi, ping yi, weng 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) OR (dong di)) ya kian wing yi ((((yang dong) OR (yang yang))) OR (jeng dong)) sind ;~.
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (dong di)) ya kian wing yi ((((yang dong) or (yang yang))) or (jeng dong)) sind ;*.
