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
shi wong » shi rong, shin dong, shi ding
wong sau » wong sam, wong siu, wong shiu
hua ren » hua chen
yan shi » yan zhi, yun shik
wang » 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 OR wing) ((yang guang) OR (((yan guan) OR (yan yuan)))) hua ren yan shi wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yang guang) or (((yan guan) OR (yan yuan)))) hua ren yan shi wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yang guang) or (((yan guan) OR (yan yuan)))) hua ren yan shi wong sau ;*.
