Perhaps you should try some spelling variations:
chuc danh » chuc nganh, thuc hanh, chuc nang
chua xang » chua nang, chuc nang, chu bang
nhan dang » nhan dan, phan dang, tran dang
hung cong » nhung cong, hung cuong, phung cong
dang lan » dang van, dang dan, dang hanh
lan hung » van hung, luan chung, lan phuong
cong dan » cong san, cong tan, huong dan
toan ban » van 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: cua ((chuc danh) OR (chua xang)) - nhan dang lan hung cong dan ((toan tap) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: cua ((chuc danh) or (chua xang)) - nhan dang lan hung cong dan ((toan tap) or (toan ban))*.
