Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
yang jie » yang jin, yang di, yang jui
liu gang » liu gangs, liu yang, li gang
gang hai » dang hai, shang hai, eang hay
ying ji » ying jin, jing ji, yang jin
qian » ian, kian, jian

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

• Performing a fuzzy search may retrieve terms with similar spellings: qian rong ((ying ji) or (yang jie)) ((wang yang) or (((yao yang) OR (yang yang)))) liu gang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian rong ((ying ji) OR (yang jie)) ((wang yang) OR (((yao yang) OR (yang yang)))) liu gang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian rong ((ying ji) or (yang jie)) ((wang yang) or (((yao yang) OR (yang yang)))) liu gang hai ;*".
