Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
nhanh mang » nhanh lang, hanh mang, nhanh quang
dung cong » dung trong
chi sang » chi lang, chi chang, khai sang
mang cua » manh cua, dung cua, ban cua
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, 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 ((chi sang) OR (chieu sang)) - nhanh mang cua dung cong dan than cao~.
• Adding a wildcard symbol may retrieve word variants: doi ((chi sang) or (chieu sang)) - nhanh mang cua dung cong dan than cao*.
