Perhaps you should try some spelling variations:
thanh chuong » thanh huong, thanh cong, nhanh chong
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cao » toan ban, toan tap
cac ban » cac dan, cac van, can ban
ca ban » cua ban, can ban, co ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh chuong ((ca ban) OR (cac ban)) cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh chuong ((ca ban) OR (cac ban)) cong tan toan cao*.
