Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
chieu xanh » chieu sach, chieu sang, chieu tinh
chat trong » nhat trong, thuat trong, chat luong
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap

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: theo ((nhieu tang) OR (chieu xanh)) - hanh tinh chat trong ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((nhieu tang) or (chieu xanh)) - hanh tinh chat trong ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((nhieu tang) or (chieu xanh)) - hanh tinh chat trong ((cong dan) OR (cong tan)) toan cau*.
