Introduction to the auditorium: The back hall on the first floor of the Memorial Hall is an auditorium that can accommodate more than 1,000 people. In the middle of the rostrum is a plaster bust of Dr. Sun Yat-sen, with the "Prime Minister's Will" written in sky blue on both sides. On both sides of the rostrum are Sun Yat-sen's instructions: "The revolution has not yet succeeded, comrades still need to work hard." Around the back hall, there are marble carvings of Dr. Sun Yat-sen's famous aphorisms. The top is decorated with exquisite European reliefs. Pools, flower beds, and lawns surround the memorial hall.
