Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
canh doanh » chinh doanh, doanh doanh, kinh doanh
hanh doanh » hang doanh, chinh doanh, doanh doanh
hoc thieu » toc thieu, hoc hien
hung cong » nhung cong, hung cuong, phung cong
cong tinh » cong trinh, cong vinh, long tinh
lan hung » van hung, luan chung, lan phuong
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 chieu) OR (hoc thieu)) xanh - ((canh doanh) OR (hanh doanh)) lan hung cong tinh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (hoc thieu)) xanh - ((canh doanh) OR (hanh doanh)) lan hung cong tinh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (hoc thieu)) xanh - ((canh doanh) OR (hanh doanh)) lan hung cong tinh toan tap*.
