Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
cua truong » cua trung, xuan truong, cac truong
cua trong » cua trung, qua trong, ca trong
cong ban » cong bang, cong san, cong tan
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: hoc ((thieu xanh) OR (chieu xanh)) - thanh trung ((cua trong) OR (cua truong)) cong ban than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - thanh trung ((cua trong) or (cua truong)) cong ban than cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - thanh trung ((cua trong) or (cua truong)) cong ban than cau*.
