Perhaps you should try some spelling variations:

thieu xanh » chieu xanh, hieu manh, thien danh
trung tuan » trung thanh, trung tam, tran tuan
tuan thong » toan thong, tran thong, tuan phong
thong cong » trong cong, tong cong, thong thong
thien anh » thien danh, tien anh, thien thanh
cong san » cong tac
than cau » toan cau, than cap, thanh chau
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: hoc ((thieu xanh) OR (thien anh)) - thanh trung tuan thong cong san ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (thien anh)) - thanh trung tuan thong cong san ((than cau) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (thien anh)) - thanh trung tuan thong cong san ((than cau) or (phan cau))*.
