Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
cong manh » cong danh, duong manh, cong thanh
hanh ban » thanh ban, hang ban, hanh san
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
ban cua » ban quan

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 (chinh sach)) - hanh ban cua nhung cong manh ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chinh sach)) - hanh ban cua nhung cong manh ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chinh sach)) - hanh ban cua nhung cong manh ((toan cau) OR (toan tap))*.
