Many children took part in an old objects fair held in Beijing's Youth Lake Park on September 7. Over the years, the park has organized activities such as children's idle goods trading, cultivating children's love and responsibility and building a communication platform for them.

With the construction of Beijing's "Garden City", the park has held various public welfare activities to cultivate children's ecological and environmental awareness. It has also launched the “tiny forest chief” system, striving to promote the construction of the "Garden City" and create an atmosphere where "everyone is a gardener".
