Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
cua thuong » cua truong, cua phuong, ca thuong
hoc chieu » hoc thieu, ho chieu, hoc hien
tac phat » tam phat, tan phat, tao phat
tac pham » thuc pham, san pham

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 trang ((cua thuong) OR (cua cong)) cong ((tac phat) OR (tac pham)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh trang ((cua thuong) or (cua cong)) cong ((tac phat) OR (tac pham)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh trang ((cua thuong) or (cua cong)) cong ((tac phat) OR (tac pham)) cau*.
