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

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