Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
qiang yang » wang yang, qian yan, huang yang
yang yang » wang yang, wang yan
sun qiang » sun xifang, jun qian, sun ang
shi rong » yi rong
li cong » li rong, li song, jiu cong
wang » wing, wan

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 OR lang) ((yang liang) OR (yang yang)) sun qiang yang ((shi rong) OR (li cong)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yang liang) OR (yang yang)) sun qiang yang ((shi rong) or (li cong)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((yang liang) OR (yang yang)) sun qiang yang ((shi rong) or (li cong)) hai ;*.
