Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
nhanh long » nhanh dong, thanh long, nhanh lang
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
long cua » luong cua, cong cua, dong cua
dan than » dan chan, ban than, van than

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 xanh) OR (chieu sang)) - nhanh long cua nhung cong ((dan than) OR (van ban)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - nhanh long cua nhung cong ((dan than) or (van ban)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - nhanh long cua nhung cong ((dan than) or (van ban)) cau*.
