Perhaps you should try some spelling variations:
doanh doanh » toan doanh, doanh hoan, doanh thanh
theo chieu » theo tieu, theo chu, thi chieu
hanh doanh » hang doanh, chinh doanh, kinh doanh
tong cong » trong cong, cong cong, dung cong
ho chieu » hoc thieu, doi chieu, mot chieu
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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: ((ho chieu) OR (theo chieu)) xanh - ((hanh doanh) OR (doanh doanh)) cua tong cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - ((hanh doanh) OR (doanh doanh)) cua tong cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - ((hanh doanh) OR (doanh doanh)) cua tong cong dan than cao*.
