Perhaps you should try some spelling variations:
chieu trach » chiu trach, chien tranh, chiet tach
theo chieu » theo tieu, ho chieu, theo chu
dong thanh » truong thanh
ranh mach » trinh mach, tinh mach, ban mach
dan dong » van dong, dan dung, dao dong
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
anh anh » thanh anh, hinh anh, minh anh
cua dan » cua dang, cua ban, ca dan

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 trach - ((ranh mach) OR (anh anh)) cua dan dong thanh ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: theo chieu trach - ((ranh mach) or (anh anh)) cua dan dong thanh ((toan cau) or (toan ban))*.
