Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
dong cao » dong xiao, dan cao, dong nan
hua rest » hua ren
yang tan » yang dean, liang tan, tang tang
yang fan » zhang fan, yang dean, yang jin
hong hai » shang hai, zhong tai, dang hai
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: ((dong cao) OR (dong sin)) ya hua rest ((yang tan) OR (((yang fan) OR (yang yang)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (dong sin)) ya hua rest ((yang tan) or (((yang fan) OR (yang yang)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) or (dong sin)) ya hua rest ((yang tan) or (((yang fan) OR (yang yang)))) hong hai ;*.
