Introduction to Neiwan Theater: The predecessor of Neiwan Theater was the "Material Ping" of the "Mountain Farm" run by "Yang Shengquan" of the Yang family, which was the site where forest materials were placed at that time. In 1950, in order to consider the leisure needs of workers, a wooden two-story Japanese-style theater was planned and built. It still retains its original appearance and is currently the best preserved ancient wooden theater in Taiwan.
