Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hoc thieu » toc thieu, hoc hien
ban nhanh » ban hanh, ban nhan, nhan nhanh
ban thanh » ban hanh, ban hang
ho chieu » theo chieu, doi chieu, mot chieu
luat van » luan van, luat dan, luat va
van cong » van dong, van phong, phan cong

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: ((ho chieu) OR (hoc thieu)) xanh - hanh trinh luat van cong ((ban nhanh) OR (ban thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - hanh trinh luat van cong ((ban nhanh) OR (ban thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - hanh trinh luat van cong ((ban nhanh) OR (ban thanh)) cau*.
