What is the second couplet of the couplet "Anzhu people return to live and work in peace and contentment"?

Anzhu people live and work in peace and contentment after their return.

Volunteers volunteer to help the poor.

Reason:

1, conceptually, the bottom can cover the top. The behavior of volunteers to help the poor is higher than that of those who are prepared for danger in times of peace, which conforms to the mainstream of the times;

2. In antithesis, the noun volunteer is relative to the person who is prepared for danger in times of peace, the verb goes back and forth, and happiness is relative to poverty alleviation;

Generally speaking, couplets are neat.
