Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
chih hang » chin chang, shih huang, chih yung
hang rong » zhang rong, zheng rong, thang long
rong wong » hong wang
yan wang » yuan wang, yang yang, qian wang
wong siu » wong shiu, kong siu, wong sau

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 liang) OR (yan wang))) OR (yang guang)) lin chih hang rong wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((((yan liang) or (yan wang))) or (yang guang)) lin chih hang rong wong siu ;*.
