Perhaps you should try some spelling variations:
nhung luong » hung luong, nhung huong, nhung tuong
hanh trinh » canh tranh, hanh chinh
thieu manh » hieu manh, tien manh, trieu minh
hoc thieu » toc thieu, hoc hien
minh tuan » anh tuan
ninh toan » tinh toan, hinh toan, minh toan
nin toan » tinh toan

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: hoc thieu manh - ((minh tuan) OR (hanh trinh)) va nhung luong ((ninh toan) OR (nin toan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - ((minh tuan) or (hanh trinh)) va nhung luong ((ninh toan) OR (nin toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - ((minh tuan) or (hanh trinh)) va nhung luong ((ninh toan) OR (nin toan)) ban*.
