Introduction to the front exhibition hall: The exhibition hall on the first floor of the East Building is adjacent to the front yard and is an outer corridor. Four two-story circular columns are made of concrete structure, with a base diameter of 1 meter. They are magnificent and the column heads are decorated with floral reliefs. Extremely gorgeous. There is a plaque inscribed by Deng Xiaoping "In memory of Liu Shaoqi" embedded directly above the door of the exhibition hall.
