Perhaps you should try some spelling variations:
nhung thoi » nhung thi, phung thi, nhung loi
bien tram » bien tran, bien tap, bien rau
trong ban » trong san, trong tan, trong quan
bien tam » bien tap, bien tiem, bien tran
ban hang » ngan hang
que van » quy van, quyet van, quan van
qua van » quan van, qua ban, qua san

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 bai)) ((que van) or (qua van)). ((bien tram) OR (bien tam)) trong ban hang~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung thoi) OR (nhung bai)) ((que van) OR (qua van)). ((bien tram) OR (bien tam)) trong ban hang.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung thoi) or (nhung bai)) ((que van) or (qua van)). ((bien tram) OR (bien tam)) trong ban hang".
• Adding a wildcard symbol may retrieve word variants: ((nhung thoi) or (nhung bai)) ((que van) or (qua van)). ((bien tram) OR (bien tam)) trong ban hang*.
