Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tran » thanh trang, thanh toan, thanh tra
hoc thieu » toc thieu, hoc hien
van nhung » van nhuong, va nhung, van hung
van huong » van chuong, van phuong, ban huong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 - thanh tran ((van nhung) OR (van huong)) cong dan than cao~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tran ((van nhung) or (van huong)) cong dan than cao*.
