Perhaps you should try some spelling variations:
zhang ting » zhang ming, zhang jing, zhang ping
wang yang » wang yan, wang liang, wang yanling
chang tin » chang min, zhang tian, chang ann
wong shiu » wong siu, cong shu, song shin
yang hua » wang hua, yang hui, yang jui
ying hua » ming hua, wang hua, ying zhu

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: wang yang ((yang hua) OR (ying hua)) irene ((chang tin) OR (zhang ting)) wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang hua) or (ying hua)) irene ((chang tin) OR (zhang ting)) wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang hua) or (ying hua)) irene ((chang tin) OR (zhang ting)) wong shiu ;*.
