Perhaps you should try some spelling variations:
wang liang » wang yang
liu gangs » liu gang, liu yang
gangs hai » dang hai
qian yan » qian jun, qian yi
yang jun » yang jui, pang jun, yang jin
yang jie » yang jin, yang jui, yang xi
tan ying » fan ying, ran ying, tan yang

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 ((yang jun) or (((yang jie) OR (yang di)))) ((wang liang) or (tan ying)) liu gangs hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan ((yang jun) OR (((yang jie) OR (yang di)))) ((wang liang) OR (tan ying)) liu gangs hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan ((yang jun) or (((yang jie) OR (yang di)))) ((wang liang) or (tan ying)) liu gangs hai ;*".
