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