Perhaps you should try some spelling variations:
yang sudan » kano sudan, yang rudai
sudan chen » sudan ch
wang yang » wang yan, wang liang, wang yanling
wei wang » wei yang, wen wang, wei shang
yang jui » yang xi, yang yi
yang jin » yang jie, yang jun, ying jin
kong siu » kong eiu, wong siu, dong sin

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: wei wang yang sudan chen ((((((yang jui) OR (yang judy))) OR (yang di))) OR (yang jin)) kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: wei wang yang sudan chen ((((((yang jui) or (yang judy))) or (yang di))) or (yang jin)) kong siu ;*.
