Here, Chairman Mao and other leaders live for a long time, especially the central auditorium here is the place where the seven major conferences are held. This thousand-person auditorium did not have a beam and no column. At that time, there was no lifting machinery, and it was a architectural miracle to rely on manpower. There is also the vegetable plot planted by Chairman Mao himself, which fully reflects the hard work style of the time. Chairman Mao met with the American journalist Strong here to make the famous argument that all reactionaries are paper tigers.
