Perhaps you should try some spelling variations:
dong ping » dong sin, dong bin, dong jung
zhang zhi » zhong zhi, wang zhi, zhang wei
dan yang » daun yang, tan yang, wang yang
yang kim » yong kim, kang kim, hyung kim
jang zhi » wang zhi, liang zhi, jang ho
wai yan » wang yan, wei yang
meet al » meet a, meet paul

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: ((wai yan) OR (dong ping)) ((et al) OR (meet al)) dan yang kim ((jang zhi) OR (zhang zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (dong ping)) ((et al) or (meet al)) dan yang kim ((jang zhi) OR (zhang zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wai yan) or (dong ping)) ((et al) or (meet al)) dan yang kim ((jang zhi) OR (zhang zhi)) ;*.
