Perhaps you should try some spelling variations:
chen shuang » chen chuan, chen huigang, chen chuanfu
chen chung » chen chuling, chen chuan, chen dung
mae jeong » lee jeong, min jeong
jeong su » jeong _, jeong mi, jeong 情
guan li » gan li, yuan li, yuan lin
ban zi » ban ji, yan zi
wang » wing, wan, lang

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 yan ((guan li) OR (ban zi)) ((chen chung) OR (chen shuang)) mae jeong su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((guan li) or (ban zi)) ((chen chung) OR (chen shuang)) mae jeong su ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((guan li) or (ban zi)) ((chen chung) OR (chen shuang)) mae jeong su ;*.
