Perhaps you should try some spelling variations:
thieu nganh » hieu nganh, trien nganh, nghiep nganh
hanh trinh » canh tranh, hanh chinh
hoc thieu » toc thieu, hoc hien
trinh va » trinh van, trinh vat, trinh ve
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu nganh - hanh trinh va nhung ((cong dan) OR (cong san)) than cap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu nganh - hanh trinh va nhung ((cong dan) OR (cong san)) than cap*.
