Perhaps you should try some spelling variations:
rene jing » zeng jing
yan yuan » fang yuan, nan yan, yan clan
yan guan » gan guan, yang guang, yihan guan
hua rene » hua ren, juan rene
wong sau » wong shiu, wong lai, kong sar
wong sam » wong lai, kong sar, von sam
wong siu » wong shiu, kong siu, wong siew
jing ji » ying jin

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: wing ((yan yuan) OR (yan guan)) hua rene jing ji ((((wong sau) OR (wong sam))) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan yuan) OR (yan guan)) hua rene jing ji ((((wong sau) or (wong sam))) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((yan yuan) OR (yan guan)) hua rene jing ji ((((wong sau) or (wong sam))) or (wong siu)) ;*.
