Perhaps you should try some spelling variations:
thanh truong » thanh trung, thanh thuong, thanh tung
truong khoa » tuong khoa, trung khoa, luong khoa
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
khoa dung » hoc dung, khoa cong
dung cong » dung trong
cong ban » cong bang, cong san, cong tan
phap cau » pha cau, phap ca, phap cac
phan cau » phan dau, phan cac, phan tu

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: ho ((chieu xanh) OR (chieu sang)) - thanh truong khoa dung cong ban ((phap cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - thanh truong khoa dung cong ban ((phap cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - thanh truong khoa dung cong ban ((phap cau) OR (phan cau))*.
