Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
nhanh lang » nhanh quang, nhanh thang, nhan dang
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
lang cua » mang cua, hang cua, long cua
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
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 ((chieu sang) OR (chieu xanh)) - nhanh lang cua nhung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (chieu xanh)) - nhanh lang cua nhung cong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) OR (chieu xanh)) - nhanh lang cua nhung cong dan ((toan cau) or (toan cao))*.
