Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, thi chieu
hanh dung » thanh dung, anh dung, hanh dong
dung cong » dung trong
theo chu » cho chu, chao chu, theo yeu
dung qua » duong qua, dung quan, dung cua
qua dung » quang dung, su dung, qua song
cong dan » cong san, cong tan, huong dan
toan ban » van 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 (theo chu)) xanh - hanh dung qua dung cong dan ((toan tap) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo chu)) xanh - hanh dung qua dung cong dan ((toan tap) or (toan ban))*.
