Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
mot chieu » doi chieu, ho chieu
thai cong » tai cong, thi cong, thanh cong
trung ha » trung hoc, trung cap
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((mot chieu) or (theo chieu)) xanh - manh ((trung ha) OR (trung tam)) thai cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo chieu)) xanh - manh ((trung ha) OR (trung tam)) thai cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo chieu)) xanh - manh ((trung ha) OR (trung tam)) thai cong dan toan ban*".
