In the planning of cross-domain aesthetic courses, the Victory Team of the 113th academic year will start from "space". Whether it is concrete, abstract, virtual or psychological space, etc., it is worth discussing with students. The cross-domain curriculum design includes mathematics, comprehensive and language areas; the topic integration covers SEL and life education topics. The final performance will be presented in the form of a "class concert", which is an art feast that attracts much attention every year.
