If windows are the eyes of a building, then the window frames highlight the romance of life. The course opens the children's soul ~ eyes, rationally explore the knowledge of windows, perceptually explore the local window craftsmanship, use windows to read the social and cultural evolution of Lukang in different periods, visit the alleys and immerse yourself in the cultural customs. Look at the geometry of the window from a mathematician's perspective, and look at the outdoor scenery formed by the windows inlaid everywhere from an artist's perspective. Windows also gather light, and Jiang Xun said, "Sound is like a kind of light, flying in the air." Open your ears and listen to the window scenery, which hints or sets off people's mood or the atmosphere of the scene. Use sound to perceive and express yourself and communicate with others. Interact and understand other people’s ideas. The window is an extension of the field of vision and a perspective of viewing. The course uses the body to express the two worlds inside and outside the window, explore one's role in the team, and enhance interpersonal communication. Opening the window is like opening oneself. Window, reason and sensibility.
