Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
cong dan » cong san, cong tan, huong dan
phan dau » phan tu, hang dau
than cap » khan cap, thanh lap, thanh cac
va dang » van dang, va nang, da dang
va lang » va nang, hoa lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu tinh - canh tranh ((va dang) OR (va lang)) cong dan ((phan dau) or (than cap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - canh tranh ((va dang) OR (va lang)) cong dan ((phan dau) OR (than cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - canh tranh ((va dang) OR (va lang)) cong dan ((phan dau) or (than cap))*".
