Perhaps you should try some spelling variations:
yan guan » gan guan, yan yuan, yang guang
yan clan » das clan, yan yuan
song min » song ming, gong min, jong min
yan tan » tan tan, yan wang, yan yuan
hua bin » hua ban, huang bin
zhang a » zhang ya, zhang _, zhang j
zhang i » zhang ii, zhang li, zhang si
wang » wing, wan, lang

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 ((((yan tan) OR (yan guan))) OR (yan clan)) hua bin ((zhang a) OR (zhang i)) song min ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan tan) or (yan guan))) or (yan clan)) hua bin ((zhang a) OR (zhang i)) song min ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan tan) or (yan guan))) or (yan clan)) hua bin ((zhang a) OR (zhang i)) song min ;*.
