Perhaps you should try some spelling variations:
doanh thanh » danh thanh, doanh nhan, dinh thanh
chieu xanh » chieu sach, chieu sang, chieu tinh
canh doanh » hanh doanh, chinh doanh, doanh doanh
ho chieu » theo chieu, hoc thieu, doi chieu
cong ban » cong bang, cong san, cong dan
cong tan » cong tac, cong san, cong thanh
hang cao » hoang cao, nang cao, hang ca

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 xanh - ((canh doanh) OR (doanh thanh)) va nhung ((cong ban) OR (cong tan)) hang cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((canh doanh) or (doanh thanh)) va nhung ((cong ban) OR (cong tan)) hang cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((canh doanh) or (doanh thanh)) va nhung ((cong ban) OR (cong tan)) hang cao*.
