Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, chieu xanh
cua nhung » va nhung
cong doan » cong dan, cong hoan, dong doanh
danh bat » doanh bat, dinh ba
doan van » doan va, hoang van, luan van
anh bai » sach bai, hinh bai

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((anh bai) OR (danh bat)) cua nhung cong doan van ban~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((anh bai) OR (danh bat)) cua nhung cong doan van ban*.
