Perhaps you should try some spelling variations:
yung chen » yu chen, yulu chen, kang chen
wang ban » wang yan, wang dan, wang yang
yun chen » yu chen, yuan cheng, yulu chen
yang jie » yang jin, yang jui, yang yi
kong siu » kong eiu, wong siu, dong sin
yang xi » yang yi, yang jui
radu » raju, nadu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ban radu ((yun chen) OR (yung chen)) ((((yang xi) or (yang di))) or (yang jie)) kong siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ban radu ((yun chen) OR (yung chen)) ((((yang xi) OR (yang di))) OR (yang jie)) kong siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ban radu ((yun chen) OR (yung chen)) ((((yang xi) or (yang di))) or (yang jie)) kong siu ;*".
