Now children's psychological fragility may be caused by the following aspects:

1. Changes in educational methods: Nowadays, parents pay more attention to their children's emotional experience and free development, and are often tolerant and conniving at their children's mistakes and shortcomings. This kind of education will gradually make children have a kind of "uncritical" psychology and can't bear negative comments.

2. Changes in social environment: With the changes in material conditions, the environment in which children live and study now becomes more comfortable and convenient than before, but at the same time it lacks some tests and challenges. When children are frustrated and stressed, they are often more likely to become anxious or inferior, and feel insecure about their abilities.

3. Popularization of information technology: Today's children live in an information age, and they are exposed to a lot of information, but the quality of this information is mixed. Some bad information will have a negative impact on children's mental health, especially some cyber violence and cyber bullying.

4. Expectation pressure from family, society and school: Nowadays, families and society often expect children to achieve better grades and higher comprehensive quality. Such pressure may be too heavy for children, causing psychological burden. The school's study arrangement and examination system will also have an impact on children's psychology.

In a word, there are many reasons for children's psychological fragility, which need the common concern and solution of parents and educators. Parents should guide their children to look at themselves correctly and pay attention to their emotional experience and cognitive development; Educators should pay attention to children's mental health and provide more healthy, balanced and effective educational resources.
