Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, seung yeon
sang minh » kang minah, anh minh, song min
rene sang » lee sang
jeong seo » hong seo, jeong su
ting hai » dang hai, hong hai, king has
hai rene » hai ren, i rene, ii rene
feng » eng, fang

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: ((feng juan) OR (wang yan)) ting hai rene sang minh ((jeong seo) OR (jeong yeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((feng juan) or (wang yan)) ting hai rene sang minh ((jeong seo) OR (jeong yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((feng juan) or (wang yan)) ting hai rene sang minh ((jeong seo) OR (jeong yeon)) ;*.
