Given the above summary, write a detailed text in English for it.
The cage is a safe space for your parakeet, but you want him or her to be in the presence of your family enough to be used to seeing and hearing people. Be sure, however, that this is a place where the bird can get rest when wanted—budgies need 10-12 hours of sleep per night. Cover the cage when your budgie sleeps—this blocks his or her vision and keeps drafts at bay—and be sure no loud noises will startle your parakeet where it's sleeping Once the bird seems comfortable in his or her cage where you have put it—and especially where they will be in the presence of people on a regular basis—start getting closer to the cage each day. Move slowly when you come near the cage so as not to frighten your parakeet.  Talk softly to the bird when you are near the cage. Avoid sudden movements. Spend plenty of time near the cage—the more the better. Your parakeet will know that you know he or she is there. You are essentially the bird's flock, with which he or she would spend all their time with in the wild, so the more time you spend with your budgie, the better. If it moves away, don't move your hand; instead, keep it there and talk to the bird or read a book.  The point is to get the bird used to your hand and your presence. Be sure not to scare the bird.
