Perhaps you should try some spelling variations:
yang yang » wang yang
yang jing » wang jing, huang jing, yang liang
fang hari » dang hai, fang ri
yan yuan » yan guan, fang yuan, nan yan
qian yan » qian jun, qian yi
yang jin » yang jie, yang jun, ying jin
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 ((((yan yuan) OR (yang yang))) OR (qian yan)) tan ((yang jing) OR (yang jin)) fang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yan yuan) or (yang yang))) or (qian yan)) tan ((yang jing) OR (yang jin)) fang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yan yuan) or (yang yang))) or (qian yan)) tan ((yang jing) OR (yang jin)) fang hari ;*.
