Perhaps you should try some spelling variations:
yuan zhang » yan zhang, yuan chang, xuan thang
kang minah » sang minh
dong yuan » don juan, dong hua, dong nan
jeong seo » jeong yeon, jeong su
wei rene » i rene, ii rene, wei ben
iii rene » ii rene, iii gene, iii reale
hong » long

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: dong yuan zhang ((wei rene) OR (iii rene)) kang minah ((jeong seo) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yuan zhang ((wei rene) OR (iii rene)) kang minah ((jeong seo) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yuan zhang ((wei rene) OR (iii rene)) kang minah ((jeong seo) or (hong seo)) ;*.
