Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, chieu xanh
tuong cua » truong cua, huong cua, thong cua
tang cua » mang cua, hang cua, tang luan
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 xanh - manh ((tang cua) OR (tuong cua)) nhung cong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - manh ((tang cua) or (tuong cua)) nhung cong dan than cap*.
