Perhaps you should try some spelling variations:

chieu sang » chieu sach, chieu xanh, hieu lang
hien hanh » dieu hanh
cua nhung » va nhung
anh nang » ganh nang, anh bang, anh dang
nang cua » mang cua, hang cua, nang dua
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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: hoc ((hien hanh) OR (chieu sang)) - anh nang cua nhung cong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien hanh) or (chieu sang)) - anh nang cua nhung cong dan than cap*.
