Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
yan yuan » yan guan, fang yuan, nan yan
li zhang » _ zhang
gong min » jong min, song min, gong meng
yan tan » tan tan, yan clan, yan guan
zhang a » zhang ya, zhang _, zhang i
hua li » bohua li
a gong » a gongo

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: wing ((((yan tan) OR (((yang guang) OR (yang liang))))) OR (yan yuan)) hua li zhang a gong min ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((((yan tan) or (((yang guang) OR (yang liang))))) or (yan yuan)) hua li zhang a gong min ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((((yan tan) or (((yang guang) OR (yang liang))))) or (yan yuan)) hua li zhang a gong min ;*.
