Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
yang jing » wang jing, yang jin, huang jing
zhong zhi » zhang zhi, hong ghi, zhong tai
hua t'an » huan t'an, hua ban
yang lin » yang jin, wang lin, yang liang
yang li » yang di, yang xi, yang yi

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) OR (yang yang)) ya hua t'an ((yang jing) OR (((yang li) OR (yang lin)))) zhong zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang yang)) ya hua t'an ((yang jing) or (((yang li) OR (yang lin)))) zhong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang yang)) ya hua t'an ((yang jing) or (((yang li) OR (yang lin)))) zhong zhi ;*.
