Perhaps you should try some spelling variations:
chua nang » chuc nang, chua xang, cuu nang
dang cong » dung cong
kha nang » phap nang, ky nang, ki nang
mang cua » manh cua, dung cua, cong cua
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan
ban cua » ban quan

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 ((chua nang) OR (kha nang)) - nhanh ((mang cua) OR (ban cua)) dang cong dan phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua nang) or (kha nang)) - nhanh ((mang cua) OR (ban cua)) dang cong dan phan tu~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua nang) or (kha nang)) - nhanh ((mang cua) OR (ban cua)) dang cong dan phan tu*.
