Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
tranh cua » doanh cua
manh cua » doanh cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 chieu tinh - hanh ((tranh cua) OR (manh cua)) nhung ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - hanh ((tranh cua) OR (manh cua)) nhung ((cong dan) or (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - hanh ((tranh cua) OR (manh cua)) nhung ((cong dan) or (cong tan)) toan cao*.
