Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chuc danh » chuc nganh, thuc hanh, chuc nang
trung cua » truong cua, trung tuan, trung cap
chu manh » ho manh, chu han, chu van
mang cua » manh cua, dung cua, ban cua
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan tap » toan 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: theo ((chuc danh) OR (chu manh)) - hanh ((mang cua) OR (trung cua)) nhung cong dan toan tap~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chu manh)) - hanh ((mang cua) or (trung cua)) nhung cong dan toan tap*.
