Perhaps you should try some spelling variations:
truong quan » trong quan, thong quan, luong quan
truong cua » truong ca, truong cao, huong cua
trong ban » trong san, trong tan, trong quan
khi xanh » khia canh, thi hanh, thi anh
ban than » ban thanh, van thanh, ban hang
than cau » toan cau, phan cau, 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: doi khi xanh - thanh ((truong cua) OR (truong quan)) dung trong ban than cau~.
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - thanh ((truong cua) or (truong quan)) dung trong ban than cau*.
