Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tra
tuan nhung » tuan hung, thuat nhung, tranh nhung
quan nhung » qua nhung, cua nhung, luan chung
duong van » duong va, luong va, dang van
van thang » van thanh, van khang, van hang
thang cau » hang cau, thong cau, thanh chau

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) OR (chieu xanh)) - thanh tran ((tuan nhung) OR (quan nhung)) duong van thang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chieu xanh)) - thanh tran ((tuan nhung) OR (quan nhung)) duong van thang cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - thanh tran ((tuan nhung) OR (quan nhung)) duong van thang cau*.
