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