Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
bohun li » bohua li
gong min » jong min, song min, gong meng
yan tan » tan tan, yan clan, yan guan
nan yan » nan ya, wang yan, qian yan
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 (yang guang))) OR (nan yan)) bohun li ((zhang a) OR (zhang i)) gong min ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan tan) or (yang guang))) or (nan yan)) bohun li ((zhang a) OR (zhang i)) gong min ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan tan) or (yang guang))) or (nan yan)) bohun li ((zhang a) OR (zhang i)) gong min ;*.
