Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
chinh va » chinh tai, hanh va, tinh va
chinh ta » chinh tai, chinh tri
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
toan ban » van ban

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 ((chinh va) OR (chinh ta)) nhung ((cong tan) OR (cong san)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - hanh ((chinh va) or (chinh ta)) nhung ((cong tan) or (cong san)) toan ban*.
