Nicknames shorten the distance: this kind of address is more common in primary school training institutions, such as so-and-so baby, or the last word of the name is stacked, such as Lili and Hao Hao, or the last two words of the three-word name are called.

Such a title will make children feel that teachers, like their own family, can quickly close the distance, attract their attention and make them like it. But this name is not suitable for schools. After all, there are many children with the same name now, so it is not convenient to call them, such as Zi Han and Haoran, and the students themselves are not sure who to call them.

A special education school is a compulsory education institution organized by the government, enterprises, institutions, social organizations, other social organizations and individual citizens according to law, which is specially implemented for disabled children and adolescents.
