The vitality of the square comes from the generation of people's diversified activities, and the generation of diversified activities relies on the setting of multiple functions. Therefore, in order to revitalize the square space, it is necessary to diversify the design of the square space to attract users with different needs to carry out diversified social activities. For example, amusement facilities such as slides and rock climbing can be provided for children. For young people, you can add stimulating activities, such as parkour and skateboarding, and for the elderly, you can add fitness equipment or cultural activities, such as chess and opera, to improve the cultural atmosphere of the square. At the same time, the use of disabled persons should be considered, and barrier-free plazas should be designed to reflect respect and care for disadvantaged groups.
