Perhaps you should try some spelling variations:
dong thanh » truong thanh
hanh trinh » canh tranh, hanh chinh
doan dong » doan duong, dan dong, doan cuong
he nhung » hee nhung, ve nhung, hien nhung
me nhung » ve nhung, ma nhung, my nhung
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: doan dong thanh - hanh trinh ((he nhung) OR (me nhung)) cong dan ((toan ban) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: doan dong thanh - hanh trinh ((he nhung) or (me nhung)) cong dan ((toan ban) or (toan tap))*.
