Perhaps you should try some spelling variations:
nhuong cong » nhung cong, duong cong, thong cong
luong cong » dung cong, trong cong, cong cong
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 han » van hanh, van phan, van nhan
han tap » han tai, toan tap, nhan tai

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) OR (luong cong)) van han 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) OR (luong cong)) van han tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (kha nang)) - nhanh quang van ((nhuong cong) OR (luong cong)) van han tap*.
