Perhaps you should try some spelling variations:
kong hang » kong heng, kong hong, kong land
dang hadi » dang hai
yan yuan » fang yuan, nan yan, yan clan
yan guan » gan guan, yang guang, yihan guan
kai yang » kai fang, yao yang, dan yang
yang jui » yang judy, yang di, yang xi
wan yan » wang yan, nan yan, wai yan

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: wan yan ((yan yuan) OR (yan guan)) kai yang jui ((kong hang) OR (dang hadi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((yan yuan) or (yan guan)) kai yang jui ((kong hang) or (dang hadi)) ;*.
