Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cua tinh
canh manh » lanh manh, canh tranh, cach mang
manh cua » doanh cua, ban cua
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
ho chau » ha chau, ho chu, o chau

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 chau tinh - canh manh cua ((nhung cong) OR (trong cong)) dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - canh manh cua ((nhung cong) or (trong cong)) dan ((toan cau) or (toan ban))*.
