Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan huang » yan guan, yan liang, yan wang
chih hang » chin chang, shih huang, chih yung
hang rong » zhang rong, zheng rong, thang long
wong siu » wong shiu, kong siu, wong siew
wong sau » wong sam, wong shiu, wong lai
wang » wing, 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 wan) ((yan huang) OR (yang guang)) lin chih hang rong ((wong siu) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((yan huang) or (yang guang)) lin chih hang rong ((wong siu) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((yan huang) or (yang guang)) lin chih hang rong ((wong siu) OR (wong sau)) ;*.
