Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
cuu phuong » cac phuong, thu phuong
chieu sach » chinh sach, chiet tach, chieu sang
chuc danh » chuc nganh, thuc hanh, chuc nang
anh tang » anh dang, anh nang, anh sang
anh bang » anh hoang, anh quang, tinh bang
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van 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: theo ((chuc danh) OR (chieu sach)) - ((anh tang) OR (anh bang)) cuu phuong cong van toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu sach)) - ((anh tang) or (anh bang)) cuu phuong cong van toan cao*.
