Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
cua truong » cua trung, xuan truong, cac truong
cua phuong » cuu phuong, cuc phuong, luan phuong
cua huong » cua thuong, cua cong, cua nhung
dong tac » cong tac, dong tai, dong bac
tac than » tac thanh, tam than, tac nhan
than cau » toan cau, phan cau, 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: theo chieu xanh - thanh trung ((((cua truong) OR (cua huong))) OR (cua phuong)) dong tac than cau~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh trung ((((cua truong) or (cua huong))) or (cua phuong)) dong tac than cau*.
