How long is the elder brother listening to the reciprocating machine?

My brother usually listens to the reciprocator for an hour, and then rests half an hour, but if you want to let it learn well, it is best to adjust it for 30 minutes every morning and evening.If you want to let it learn other birds, you need to hang it with other birds in the early morning, and put down the cage cloth at the same time. You can learn in 2-3 months.If you want to let it learn human language, you need to start from the young bird, teach it to speak in the morning, and learn to eat it once.
