Perhaps you should try some spelling variations:
dinh tuan » binh thuan, dinh tung, anh tuan
bin zhang » binh thang, li zhang, jia zhang
huang bin » huang lin, huang jing, huang ting
fang yuan » wang yuhan, wang yan, meng yuan
yan guan » gan guan, yan yuan, yang guang
lee jin » lee min, lee jen, lee yejin
lee jia » lee jean, lee mina

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 ((((fang yuan) OR (yan guan))) OR (dinh tuan)) huang bin zhang ((lee jin) OR (lee jia)) ji ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((fang yuan) or (yan guan))) or (dinh tuan)) huang bin zhang ((lee jin) OR (lee jia)) ji ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((fang yuan) or (yan guan))) or (dinh tuan)) huang bin zhang ((lee jin) OR (lee jia)) ji ;*.
