Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
thong cua » thong quan, huong cua
dung cong » dung trong
manh cua » doanh cua, ban cua
thong tu » phong tuc, thong tin, thong ke
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » toan cao, toan ban, toan tap

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 xanh - hanh ((manh cua) OR (((thong cua) OR (thong tu)))) dung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh ((manh cua) or (((thong cua) OR (thong tu)))) dung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((manh cua) or (((thong cua) OR (thong tu)))) dung cong tan toan cau*.
