Perhaps you should try some spelling variations:
nhanh mang » nhanh lang, nhanh quang, nhanh thang
chieu sang » chieu sach, chieu xanh, hieu lang
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
hanh mang » hanh trang, nhanh lang, thanh hang
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
phan cau » phan dau, phan cac, phan lap

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 chieu sang - ((hanh mang) OR (nhanh mang)) cua nhung cong dan ((phan cau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - ((hanh mang) OR (nhanh mang)) cua nhung cong dan ((phan cau) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - ((hanh mang) OR (nhanh mang)) cua nhung cong dan ((phan cau) or (phan tu))*.
