Perhaps you should try some spelling variations:
thanh ban » thanh san, thanh bac, thanh bai
thanh van » thanh san, thanh toan, thanh phan
dung cong » dung trong
theo chu » theo chieu, cho chu, chao chu
chu xang » chua xang, chu bang, chuc nang
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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 xang - ((thanh ban) OR (thanh van)) cua dung cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xang - ((thanh ban) or (thanh van)) cua dung cong tan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xang - ((thanh ban) or (thanh van)) cua dung cong tan ((toan cau) OR (toan tap))*.
