Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tran » thanh trang, thanh toan, thanh tra
hoc thieu » toc thieu, hoc hien
cua nhung » va nhung
anh bang » anh hoang, anh quang, tinh bang
cua dang » cua ban
tran van » luan 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 thieu xanh - anh bang ((((cua nhung) OR (cua dang))) OR (cua cong)) cong thanh tran van~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - anh bang ((((cua nhung) or (cua dang))) or (cua cong)) cong thanh tran van*.
