Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
chuc nganh » chuc nang, hoc nganh, cac nganh
nhung cong » dung cong, thong cong, hang cong
chuc danh » thuc hanh, chuc nang, thuc dan
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
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 (chuc nganh))) OR (chieu xanh)) - thanh trung cua nhung cong van toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chuc danh) OR (chuc nganh))) or (chieu xanh)) - thanh trung cua nhung cong van toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chuc danh) OR (chuc nganh))) or (chieu xanh)) - thanh trung cua nhung cong van toan tap*.
