Family upbringing refers to the way of discipline for children, the way of upbringing of the educatee dominates, and the bad way of upbringing will also affect the bad habits of teenagers. From the knowledge I have learned, I roughly summed up the three most harmful forms of bad education: the first kind of domineering: willful parents who do not reason with their children, always ignore the existence of their children's personality. This parenting is too strict, too simple and rude, and does not care about children's self-esteem. Children tend to form inferiority complex, but also lead to children lying, destruction, and even theft and other acts. The second type of apathy: some parents who are passionate about their career or have a bad relationship with their children may not be able to discipline or take care of their children. Children are prone to apathy, selfishness and loneliness. The third type of doting: the main performance is that parents always meet any child's requirements, never against the child's will. Children's requirements will always be satisfied, but it is precisely the cause of harm to children, children's requirements for parents, parents never think about whether correct, just to satisfy. But over time, it will have a great negative impact on children's personality and mental health. Children are easy to form willful, selfish, domineering and many other bad characteristics.
