Perhaps you should try some spelling variations:
chen sang » chen yang, chen wang, chen shuang
sang minh » kang minah, anh minh, song min
jeong 情 » jeong _, jeongui 情, jeong su
qian yan » qian jun, qian yi
jeong mi » jeong _, jeong su, jong min
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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: qian yan ((yang xi) OR (yang yi)) chen sang minh ((jeong 情) OR (jeong mi)) ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan ((yang xi) or (yang yi)) chen sang minh ((jeong 情) or (jeong mi)) ;*.
