Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh tranh » canh tranh, hanh trinh, hanh trang
chau tinh » cuu tinh, ha tinh, cua tinh
tranh cua » doanh cua, manh cua
tong cong » cong cong, dung cong, dang cong
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap
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 - hanh tranh cua ((nhung cong) OR (((trong cong) OR (tong cong)))) dan than cau~.
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - hanh tranh cua ((nhung cong) or (((trong cong) or (tong cong)))) dan than cau*.
