Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
fang dong » jeng dong
yan tang » yan wang, tang tang, yan zhang
jia fang » xia fang, jia zhang, jing fang
wan yan » wang yan, nan yan, wai yan
sin » sign, sind, skin

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: ((wan yan) OR (dong di)) nan ((((yan tang) OR (yan liang))) OR (yang yang)) jia fang dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (dong di)) nan ((((yan tang) OR (yan liang))) or (yang yang)) jia fang dong sin ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong di)) nan ((((yan tang) OR (yan liang))) or (yang yang)) jia fang dong sin ;*.
