Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
wang liang » wang yang
yan guan » gan guan, yan yuan, yihan guan
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
song sam » wong sam, kong sar, song pae
hua ren » hua chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang ((((yang guang) or (wang liang))) or (yan guan)) hua ren ((yang jin) OR (yang jun)) song sam ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((((yang guang) OR (wang liang))) OR (yan guan)) hua ren ((yang jin) OR (yang jun)) song sam ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((yang guang) or (wang liang))) or (yan guan)) hua ren ((yang jin) OR (yang jun)) song sam ;".
• Adding a wildcard symbol may retrieve word variants: lang ((((yang guang) or (wang liang))) or (yan guan)) hua ren ((yang jin) OR (yang jun)) song sam ;*.
