Perhaps you should try some spelling variations:
yuan ping » yuan ming, yuan ting, yuen ping
xi zhang » li zhang, xiao zhang, bin zhang
kong siu » kong eiu, wong siu, dong sin
dong di » dong sin
ya yuan » yan yuan
xi kang » jin kang
yu yang » du yang, yi yang, yu fang
wang » wing, wan, lang

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 yan) OR (dong di)) ya yuan ping ((((xi kang) OR (xi zhang))) OR (yu yang)) kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong di)) ya yuan ping ((((xi kang) OR (xi zhang))) or (yu yang)) kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dong di)) ya yuan ping ((((xi kang) OR (xi zhang))) or (yu yang)) kong siu ;*.
