(A) the crisis of social identity
Under the dual household registration system in urban and rural areas, children are labeled as "citizens" and "farmers" at birth, which easily leads to the crisis of social identity of migrant children. Although with the support of national policies, migrant children have gradually achieved "academic success" in their places of migration, they will soon face a new problem, that is, it is difficult to integrate into the new school or social environment. Although the explicit unfairness they face is gradually decreasing and they enjoy the same educational rights as urban children, the invisible unfairness they suffer still exists. Most migrant children come from rural areas and live in a simple environment. They are often very sensitive to prejudice and discrimination from urban groups, and it is often difficult to correctly deal with new things or temptations. Studies show that 75.7% of migrant children feel ridiculed and satirized in their daily lives. The survey shows that the primary reason is "I am a foreigner" accounting for 67.3%, followed by "too little knowledge" accounting for 39.9%; "My family is too poor", accounting for 32%. Therefore, they often feel that they are out of place in this environment and can't adapt to the new environment well, resulting in a lot of contradictions and confusion, which in turn leads to inferiority complex.
(B) poor family economic conditions, students compare with each other.
Migrant children and urban children live and study together in school. After seeing the superior family circumstances of children in other cities, their hearts turn from envy to loss, which makes them become silent and withdrawn and gradually develop into inferiority complex [8]. However, the education level of urban migrant workers is generally not high, most of them have only junior high school or even primary school education, and some have never even attended school. Most of the occupations they are engaged in are unstable, highly mobile and have long working hours. They lack communication and communication with their children, which makes them feel insecure and dependent. Due to the lack of scientific counseling methods, when children's academic performance is not ideal, they often make inappropriate behaviors such as corporal punishment and reprimand. However, the head teachers of schools (especially those who lack full-time psychological teachers) are busy with teaching and class management every day, and have not invested more time and energy in paying attention to the psychological changes of migrant children. The above reasons lead to migrant children from early self-confidence to inferiority complex.
Negative self-evaluation
Migrant children are immature, have low cognitive ability and lack the ability to deal with problems correctly. Compared with urban children, they have low self-evaluation, always feel inferior, can't correctly understand themselves, pay attention to their shortcomings and deficiencies, but can't see the bright spot in themselves [9]. A survey found that 23.5% of migrant children think that they are inferior to others in school, 56.8% of students think that their grades are average, nothing outstanding, 44.4% of children think that their academic performance is not good, 4 1.2% of children think that their learning ability is not strong, and their evaluation of academic performance tends to be negative. After being frustrated, they often attribute themselves to lack of ability and inferiority.
