Introduction to the music stage: Located in the south of Sun Yat-sen Mausoleum Square, it is a reinforced concrete structure with a semicircular plane. The center of the circle is the stage, and a large wall is built behind the stage. It has the same principle as the Beijing echo wall to collect sound waves. In front of the pool is a semicircular lawn, where the audience can sit and enjoy singing and dancing, and can accommodate 3,000 spectators.
