There should be a distinction between netizens and friends. There are real netizens. Because we are making friends online, we can become good friends without much conflict of interest. I even felt that it was too late to meet each other and talked about everything. However, if you want to become a true friend in life, there are many restrictions, because friends in life are formed after many times of emotional training and sharing of joys and sorrows. Only when people of the same mind are connected can they become true friends. We can't say that a chance meeting is a true friend, right? We can't say that eating, drinking and having fun once or twice is a true friend, right? Therefore, there are two types of friends. One is that friends are friends and are based on mutual understanding. Second, friends become true friends, which are also a limited number that are difficult to meet in life. Such friends affect your life and become the spiritual source and intangible material wealth of your life and work.
