Perhaps you should try some spelling variations:
yihan guan » yan guan
yang guang » yang yang, yan guan, yang liang
twinn ian » wing ian
park poon » park joon
poon tan » noor tan
tan kong » tan hong
kong eiu » tonga eiu
dong di » dong sin

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: ((twinn ian) OR (dong di)) ((yang guang) OR (yihan guan)) park poon tan kong eiu ;~.
• Adding a wildcard symbol may retrieve word variants: ((twinn ian) or (dong di)) ((yang guang) or (yihan guan)) park poon tan kong eiu ;*.
