Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
phung cong » phong cong, nhung chong, dung cong
hien xanh » hien hanh, hien nhanh, chieu xanh
tung quan » tuong quan, trung quan, dung quan
danh toan » manh toan, anh toan, dan toan
toan ban » van ban

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 - thanh tung quan ((nhung cong) OR (phung cong)) danh toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - thanh tung quan ((nhung cong) or (phung cong)) danh toan ban*.
