Consider a scenario (that I constructed to convey my intends):
- We want to unify some people from different parts of a country, e.g. farmers.
- These people have similar interests.
Now, consider my concocted sentences:
We should bring people with same interests under a roof so that ... .
We should bring people with same interests under an umbrella so that ... .
The above sentences have been translated word by word from my native language. I want to know whether English speakers have same phrases including "umbrella" or "roof"? If so, I will be happy to know about it.
I know I can use the verbs like "unify", but I want to use idiomatic phrases. So, other suggestions will also be appreciated.
