It was March 28, 2018.All the teachers and students in Tangwai primary school first grade came to the squirrel tribes in Tianfu New District, and held a social practice activity, which was held every semester. Here, some children played in the colorful bubble Park, some climbed in the stimulating "rope maze", some jumped in the different size of the happy trampoline, and some shuttled in the dense pineal forest... Children were free to enjoy the natural and fresh air, to challenge all kinds of amusement projects, to enjoy children's fun and to feel the joy of group activities.
