Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yan huang » yan guan, yan liang, yan wang
yang yang » wang yang, wang yan
chih hang » chin chang, shih huang, chih yung
hang seng » fang sheng
seng dong » jeng dong, eng hong, zeng doug
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: wing ((yan huang) or (((yang guang) OR (yang yang)))) lin chih hang seng dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yan huang) OR (((yang guang) OR (yang yang)))) lin chih hang seng dong sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan huang) or (((yang guang) OR (yang yang)))) lin chih hang seng dong sin ;*".
