Perhaps you should try some spelling variations:
nhung thoi » nhung thi, phung thi, nhung loi
viet trong » viet trung, viet thong, viet huong
quen vang » quan van, que van, que lang
biet tran » bien tran, viet tran, viet trang
trong ban » trong san, trong quan, trong cac
trong tan » trong quan, trong cac, trong ca

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: nhung thoi quen vang. ((biet tran) OR (viet trong)) ((trong ban) OR (trong tan)) than~.
• Adding a wildcard symbol may retrieve word variants: nhung thoi quen vang. ((biet tran) or (viet trong)) ((trong ban) or (trong tan)) than*.
