Perhaps you should try some spelling variations:
thanh trung » thanh tung
hien khanh » hien nhanh, dien khanh, thien thanh
hien hanh » dieu hanh
chan dung » van dung, dan dung
cap dung » ap dung, cao dung, cach dung
cac toan » cac khoan, hach toan, cac thanh
toan tap » toan ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien khanh) or (hien hanh)) - thanh trung ((cap dung) OR (chan dung)) trong cac toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien khanh) OR (hien hanh)) - thanh trung ((cap dung) OR (chan dung)) trong cac toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien khanh) or (hien hanh)) - thanh trung ((cap dung) OR (chan dung)) trong cac toan tap*".
