Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, hanh trang, manh trung
hoc chieu » hoc thieu, ho chieu, hoc hien
tuan hung » tran hung, luan hung, tuan dung
hung cong » nhung cong, hung cuong, phung cong
cong ban » cong bang, cong san, cong tan
toan cao » toan ban
toan tap » toan ban

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 chieu xanh - ((hanh trung) OR (canh tranh)) tuan hung cong ban ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((hanh trung) or (canh tranh)) tuan hung cong ban ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh trung) or (canh tranh)) tuan hung cong ban ((toan cao) OR (toan tap))*.
