I think letting them enter the university for the aged is one of the best ways to prevent them from leaving the times. Go to school to learn to charge, and your knowledge will naturally be updated. In addition, being able to meet many peers, see other people's lifestyles and communicate with others in the university for the aged will help them to abandon their stubborn ideas and make them accept new things more easily. If parents want to accept new things, they must buy tablets and mobile phones, and they must be equipped with the Internet and electronic products at home. As long as you download games and video software for them on mobile phones and tablets, teach them how to play. After a long time, it goes without saying that they can keep up with the times. Especially in the current video software, all the anecdotes and interesting things can be seen in it, which can not only refresh their minds, but also promote their ideological growth. Besides, you should spend more time with your parents and talk to them about your own life and experience. Parents like to listen to their children when they are old. If you spend more time with them, they will accept new things, because if they want to talk to you, they will try their best to understand what you said, and over time, they will be able to change the status quo.
