Perhaps you should try some spelling variations:
hieu lang » chieu sang, hieu quang, nhieu tang
hanh mang » nhanh mang, hanh trang, nhanh lang
chua nang » chuc nang, chua xang, cuu nang
doi hieu » doi chieu, doc hieu, doi hien
cua nong » cua cong, cuu nong, cua dong
kha nang » phap nang, ky nang, ki nang
cong dan » cong san, cong tan, huong dan
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 hieu lang - hanh mang ((cua nong) OR (((chua nang) OR (kha nang)))) cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi hieu lang - hanh mang ((cua nong) or (((chua nang) OR (kha nang)))) cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: doi hieu lang - hanh mang ((cua nong) or (((chua nang) OR (kha nang)))) cong dan than cau*.
