Perhaps you should try some spelling variations:
thieu nganh » hieu nganh, trien nganh, nghiep nganh
hoc thieu » toc thieu, hoc hien
hanh tram » hanh trang, thanh tran, thanh tra
van nhung » van nhuong, va nhung, van hung
hanh tam » thanh tam, nhanh tam, hanh lam
cong san » cong tac
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 thieu nganh - ((hanh tram) OR (hanh tam)) van nhung ((huong dan) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu nganh - ((hanh tram) OR (hanh tam)) van nhung ((huong dan) or (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu nganh - ((hanh tram) OR (hanh tam)) van nhung ((huong dan) or (cong san)) toan cao*.
