Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
thu nghiep » thu nghiem, chu nghiep, thuat nghiep
nghiem dai » nghiep dai, nghiep tai, nghiem va
nghiem dau » nghiep dau, nghiem va, nghiem ban
hoach thu » hoach thay, doanh thu, hoach su
nghiep va » nghiep vu
sach dao » lanh dao
va hoc » van hoc

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( thu hoach thu nghiep va hoc ) or ( thuat sach dao ((nghiem dai) OR (nghiem dau)) hoc ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu hoach thu nghiep va hoc ) OR ( thuat sach dao ((nghiem dai) OR (nghiem dau)) hoc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu hoach thu nghiep va hoc ) or ( thuat sach dao ((nghiem dai) OR (nghiem dau)) hoc ))*".
