Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang
qian yan » qian jun, qian yi
yan yong » yan cong, wang yong, yang yang
tan yong » tan hong, tan kong, tan yang
ran ying » fan ying, tan ying, jin ying
yang kai » yang ka, shang kai, yang dali
yong ji » yang jie, yang jin, ying jin

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 yong ji ((((wang yang) OR (wang yanling))) or (((tan yong) or (ran ying)))) du yang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan yong ji ((((wang yang) OR (wang yanling))) OR (((tan yong) OR (ran ying)))) du yang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan yong ji ((((wang yang) OR (wang yanling))) or (((tan yong) or (ran ying)))) du yang kai ;*".
