Recognition trees are the longest-lived and particularly adaptable creatures on earth, but they are in danger of being disturbed by humans. Through thematic courses coupled with art and life technology creation, students can better understand and experience this special but ubiquitous strange creature. Trees, standing in our lives, are silent existences, but they are living creatures. In life, we often treat it like a pillar and inflict many cruel treatments on it. When it gets in the way, we prune it and remove it at will, without caring what the tree thinks. This course allows students to think from other people's perspective, how to empathize with and respond to different viewpoints and different lives, which is also a profound aesthetic attitude.
