Perhaps you should try some spelling variations:
qiang gan » qing gan, qian yan
wei qiang » wei shang
zhong zhi » zhang zhi, hong ghi, zhong tai
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang di, yang yi
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi
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 ((((yang li) OR (yang jui))) OR (yang xi)) wei qiang gan ((zhong zhi) OR (shang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yang li) or (yang jui))) or (yang xi)) wei qiang gan ((zhong zhi) or (shang hai)) ;*.
