Perhaps you should try some spelling variations:
nhung thoi » phung thi, nhung loi, nhung tri
nhung thi » phung thi, nhung tri, nhung chi
quen vang » quan van, que van, que lang
biet tran » bien tran, viet tran, viet trang
trong san » trong cac, cong san, trong ca
dong san » cong san, dong bang, dong von

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((nhung thoi) or (nhung thi)) quen vang. biet tran ((trong san) OR (dong san)) than~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung thoi) OR (nhung thi)) quen vang. biet tran ((trong san) OR (dong san)) than.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung thoi) or (nhung thi)) quen vang. biet tran ((trong san) OR (dong san)) than".
• Adding a wildcard symbol may retrieve word variants: ((nhung thoi) or (nhung thi)) quen vang. biet tran ((trong san) OR (dong san)) than*.
