The close interpersonal relationship between neighbors is a memory of the times that belongs to the generation of the case group members. However, changes in the social environment have changed their lifestyles, but not their instincts for social interaction. Therefore, another function of the organization is to provide a platform for the realization of these social interaction needs that cannot be satisfied in life. The urban middle-aged and elderly people who love square dancing had better relations with their neighbors when they were young, but now, due to the pressure of life, their neighbors have become strangers, which makes their lives feel very depressing, and they have formed a social platform of their own through square dancing. An extremely important purpose of square dancing is actually to socialize and find your own social organization.
