Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
liang sun » liang dan, liang tan, wing sun
yan guan » gan guan, yan yuan, yihan guan
jong min » gong min, song min, song ming
tan kong » tan hong
kong siu » kong eiu, wong siu, dong sin
dong di » dong sin
min tan » tin tan, wing tan

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: ((liang sun) OR (dong di)) ((yang guang) OR (yan guan)) jong min tan kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (dong di)) ((yang guang) or (yan guan)) jong min tan kong siu ;*.
