Perhaps you should try some spelling variations:
nhung duong » nhung dung, nhung huong, nhung tuong
thanh trung » thanh tung
thieu xanh » chieu xanh, thien anh, thien danh
thanh toan » thanh hoa, thanh san
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung va » truong va, trang va, trung ha

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu xanh) OR (hieu manh)) - thanh trung va nhung duong ((thanh toan) or (tinh toan)) cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (hieu manh)) - thanh trung va nhung duong ((thanh toan) OR (tinh toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - thanh trung va nhung duong ((thanh toan) or (tinh toan)) cao".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (hieu manh)) - thanh trung va nhung duong ((thanh toan) or (tinh toan)) cao*.
