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