Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh tung » thanh cong
cam trong » cam truong, cay trong, nam trong
tung cam » dung cam, trung cap, tung pham
cong ban » cong bang, cong san, cong tan
hang vau » hang dau, hang cau, hang vat

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 tung cam trong cong ban ((hang vau) OR (hang va))~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - thanh tung cam trong cong ban ((hang vau) or (hang va))*.
