The Main Hall is 26 meters high. It is a square hall, octagonal within. Four granite columns embody the four times
of proposal, made by Zhou Enlai, to achieve the grand vision of “the Four Modernizations”. Four granite columns
holding a hipped roof remind people of cattle sheds, with which water was lifted for irrigation on the ancient Jianghuai
Plain, indicating the life of Zhou Enlai to serve the people.
