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
li zhang » _ zhang
gong min » jong min, song min, gong meng
zhang a » zhang ya, zhang _, zhang i
a gong » a gongo
wang » wan, lang

You may be able to get more results by adjusting your search query.

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