Perhaps you should try some spelling variations:
thuat nghiep » thuat nhiet, thuat ghep, thuc nghiem
thuc nghiep » thuc nghiem, thu nghiem, chu nghiep
thi nghiem » thuc nghiem
nghiem xu » nghiem su, nghiem xuan, nghiem ngu
cuu kha » cuu khoa, cuu phat, cuu nhan
kha thi » khac thi, khau thi, ha thi
cua dai » cua dan, cua dang
xu hoc » tu hoc, du hoc, su hoc

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: (( cuu kha thi nghiem xu hoc ) OR ( cua dai ((thuc nghiep) OR (thuat nghiep)) dai hoc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cuu kha thi nghiem xu hoc ) or ( cua dai ((thuc nghiep) OR (thuat nghiep)) dai hoc ))~".
• Adding a wildcard symbol may retrieve word variants: (( cuu kha thi nghiem xu hoc ) or ( cua dai ((thuc nghiep) OR (thuat nghiep)) dai hoc ))*.
