Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
luong van » luong va, duong van, luong quan
luong vat » luong va, luong tai, dong vat
cua hang » cua dang, cua nhung, cua cong
tuan cau » toan cau, quan cau, tuan cu

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 tranh cua hang ((luong van) OR (luong vat)) tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - hanh tranh cua hang ((luong van) OR (luong vat)) tuan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - hanh tranh cua hang ((luong van) OR (luong vat)) tuan cau*.
