First of all, the source of sadness in all ages is the sentimentality of young people. Young people are more and more sensitive to the outside world. They learned to observe details. They look at this society with a longing for adulthood, but they find the dark side of this society at a glance. They are disappointed in the society, but they are weak and unable to change the society. They always become very sad because of some preliminary judgments on human nature.

Secondly, the development of the network. The development of network makes the above problems more prominent. The use of the Internet has further deepened their negative emotions. As an online writer, I know that venting on the internet may not achieve the effect of regulating emotions and gradually amplify some extreme emotions. When their negative emotions are vented on a certain platform, it renders a' mourning' atmosphere for the whole platform, full of disappointment and even despair.

Moreover, the emergence of some diseases is related to students' pursuit of unique psychology. Depression and autism, I don't know why young people label themselves as this mental illness for no reason. Stimulated by the negative emotions of this label, maybe a person who just pursues uniqueness will take this uniqueness seriously.

I don't like the large-scale spread of this funeral culture. I believe that the psychological maturity of human beings is an inevitable trend in the future, and the age of psychological maturity will become smaller and smaller, but the problem is that children really can't have enough rationality, self-control and pressure resistance. For them, the spread of mourning culture is a bad thing, and if they persist in this negative emotion, it will be extremely unfavorable to their personal development.

For contemporary young people,' mourning' will only waste their time for thinking and self-growth, and a positive attitude can face the unknown future.
