Introduction to the Imperial Grain Hall: Every year, the imperial grain shipped from the south of the Yangtze River passes through this town and is transported north to the capital. In order to transport and protect the imperial grain, the Qing court specially set up a garrison here in 1568 AD and built the Imperial Grain Hall to be responsible for the transportation and transfer of the imperial grain. This palace was built facing the northwest (capital city), which means it faces the emperor and can receive the emperor's gifts. Later, it gradually became a place where people burned incense and prayed for blessings. The Imperial Grain Hall was restored and rebuilt in 2010, displaying traditional tools for grain production, processing, sales, and transportation, as well as stone steles and rubbings related to the canal during the Ming and Qing Dynasties.
