Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trang » thanh trung, canh tranh, hanh trinh
trang tuan » tran tuan, trung tuan, trong tuan
tuan duong » tuyen duong, tuong duong, van duong
duong cong » dung cong, luong cong, duong trong
cong tap » cuong tap, cong tac, cong tan
doan tap » toan tap, doan cap, doan tuan

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) OR (chieu tinh)) - hanh trang tuan duong cong tap ((doan tap) OR (doanh tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - hanh trang tuan duong cong tap ((doan tap) OR (doanh tai))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - hanh trang tuan duong cong tap ((doan tap) OR (doanh tai))*.
