The original song 20 10 of the poem "What song is sung under what circumstances" was published anonymously.
The lyrics of "what song to sing in what environment" are: in what environment you want to be happy, in what environment you want to be happy. The devil will retreat and sing a song of praise happily. When you have circumstances, don't shrink back, test the truth to make you and me, examine yourself, don't look at other people's mistakes, and sing praises to the Lord patiently and humbly.
