Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
qian yan » qian jun, qian yi
tan yang » dan yang, tan ying, tan yong
gang hai » dang hai, shang hai, gang yao
yan jing » yang jing, wang jing, bian jing
eang hay » dang hai, kang han
jing ji » ying jin
gang hu » gang zhou, wang hua, wang hui

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: qian yan jing ji ((wang yang) or (tan yang)) li ((((gang hai) OR (gang hu))) or (eang hay)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan jing ji ((wang yang) OR (tan yang)) li ((((gang hai) OR (gang hu))) OR (eang hay)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan jing ji ((wang yang) or (tan yang)) li ((((gang hai) OR (gang hu))) or (eang hay)) ;".
• Adding a wildcard symbol may retrieve word variants: qian yan jing ji ((wang yang) or (tan yang)) li ((((gang hai) OR (gang hu))) or (eang hay)) ;*.
