Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
hanh dung » thanh dung, anh dung, hanh dong
dung cong » dung trong
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
ung cong » luong cong, duong cong, cuong 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 (dung cong)) thanh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chu manh)) - hanh dung luan ((ung cong) OR (dung cong)) thanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu manh)) - hanh dung luan ((ung cong) OR (dung cong)) thanh toan ban*.
