Professor Liu Qing once said in the interview program "13 Invitations": "I used to think, how could this person be like this, how could that person be like that. As I got older, I began to feel that life is full of different things. We must be able to accept that others have different worldviews and the way of thinking derived from them." When faced with different ideas and voices from their own, truly mature people will not rush to argue, change others, or force others to be their own. Instead, they have learned not to arbitrarily interfere in other people's affairs, respect differences, and not be harsh on others.
