Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
chieu tinh » trieu tinh, lieu tinh, chau tinh
doanh luan » doanh nhan
hoc chieu » hoc thieu, ho chieu, hoc hien
tuong dan » huong dan, tung dan, xuong dan
toan tai » toan tap, doanh tai, toan ban
toan cao » toan ban, toan tap

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 chieu tinh - canh ((doanh cua) OR (doanh luan)) nhung tuong dan ((toan tai) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - canh ((doanh cua) OR (doanh luan)) nhung tuong dan ((toan tai) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - canh ((doanh cua) OR (doanh luan)) nhung tuong dan ((toan tai) or (toan cao))*.
