The project is located between the municipal road and the park. It introduces people from the monochromatic landscape space to the secret back field garden step by step. People play in the sea of flowers and forget about the hustle and bustle of the city. And it allows people to experience the natural scenery without going to the field. The designer makes full use of the site conditions, changing the unfavorable factors into favorable ones, resolving the contradiction between the urban architecture and the style of the sea of flowers, bringing people to the unique city backyard.
