Perhaps you should try some spelling variations:
quan thanh » ban thanh, van thanh
hanh trinh » canh tranh, hanh chinh
doan quan » doan quang, dan quan, toan quan
he nhung » hee nhung, ve nhung, hien nhung
me nhung » ve nhung, ma nhung, my nhung
cong tan » cong tac, cong san, cong thanh
tran tap » toan tap, tran tan, tran tuan

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 quan thanh - hanh trinh ((he nhung) OR (me nhung)) cong tan tran tap~.
• Adding a wildcard symbol may retrieve word variants: doan quan thanh - hanh trinh ((he nhung) or (me nhung)) cong tan tran tap*.
