Perhaps you should try some spelling variations:
nhuong cong » nhung cong, luong cong, duong cong
van nhuong » van chuong, van phuong, van huong
chuc danh » chuc nganh, thuc hanh, chuc nang
quang van » quang ban, quan van, quang uan
kha nang » phap nang, ky nang, ki nang
van phan » van phong, van thanh, luan phan
van han » van hanh, van nhan, van hoan

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 (kha nang)) - nhanh quang van nhuong cong ((van han) OR (van phan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (kha nang)) - nhanh quang van nhuong cong ((van han) OR (van phan)) tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (kha nang)) - nhanh quang van nhuong cong ((van han) OR (van phan)) tap*.
