Perhaps you should try some spelling variations:
yang yao » yang yang, wang yan, yang yi
yang jui » yang judy, yang di, yang xi
yang hua » wang hua, yang hui, yang jun
wang hui » wang hua, wang zhi, wang wei
ying hua » ming hua, wang hua, ying zhu
chan eng » chan fong, chan kang, chan ming
eng cong » eng hong, zheng cong, eng seng

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: ((yang yao) OR (yang jui)) ((((yang hua) OR (wang hui))) OR (ying hua)) rene chan eng cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yao) or (yang jui)) ((((yang hua) OR (wang hui))) or (ying hua)) rene chan eng cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yao) or (yang jui)) ((((yang hua) OR (wang hui))) or (ying hua)) rene chan eng cong shu ;*.
