Perhaps you should try some spelling variations:
duong trong » dung trong
hanh dung » thanh dung, anh dung, hanh dong
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
ung cong » dung cong, luong cong, duong cong
toan ban » van ban

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: theo ((chu xanh) OR (chu manh)) - hanh dung luan ((ung cong) OR (duong trong)) manh toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu manh)) - hanh dung luan ((ung cong) or (duong trong)) manh toan ban*.
