Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tien thanh » tien thinh, tran thanh, den thanh
hien xanh » hien hanh, hien nhanh, chieu xanh
anh quang » anh xquang, anh quan, nhanh quang
cua nhung » va nhung
anh dang » anh dong, anh dung, anh bang
cong dan » cong san, cong tan, huong dan
dan van » dang van, doan van, dao van

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) OR (tien thanh)) - ((anh dang) OR (anh quang)) cua nhung cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (tien thanh)) - ((anh dang) or (anh quang)) cua nhung cong dan van ban*.
