Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
cong thanh » dong thanh, cong trinh, cong tan
hanh dung » thanh dung, anh dung, hanh dong
chuc danh » chuc nganh, thuc hanh, chuc nang
chu xanh » chu manh, chieu xanh, chua xang
luan ung » luan hung, luon ung, luan chung
ung cong » dung cong, luong cong, duong cong
toan ban » van ban
chu han » chu van

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