Perhaps you should try some spelling variations:
trong quan » thong quan, tong quan, thong quang
nhung thi » nhung thoi, phung thi, nhung tri
nhung loi » nhung bai, nhung bi, nhung gi
biet tran » bien tran, viet tran, viet trang
trong ban » trong san, trong tan, trong cac
que van » qua van, quy van, quyet van

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

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