Perhaps you should try some spelling variations:
nhieu tang » chieu sang, nhiet nang
hieu lang » chieu sang, hieu quang, hieu van
hanh mang » nhanh mang, hanh trang, nhanh lang
chua nang » chuc nang, chua xang, kha nang
cua dong » chua dong, cua cong, cua dang
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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: doi ((nhieu tang) OR (hieu lang)) - hanh mang ((cua dong) OR (chua nang)) huong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: doi ((nhieu tang) or (hieu lang)) - hanh mang ((cua dong) or (chua nang)) huong dan than cau*.
