Introduction to Gengsu Theater: Zhang Jian once invited Mei Lanfang and Ouyang Yuqian to perform on the same stage at the "Gengsu Theater" he founded. At that time, the scene to welcome Mei Lanfang outside the theater was very grand. Later, Zhang Jian built the "Meiou Pavilion" in the theater, and wrote a couplet inscribed with "The meeting point of the Southern and Northern schools, the present and ancient people of Wanling and Luling".
