Introduction to Hongjing: Hongjing is located by a pond about 20 meters southeast of the former site of the Central Executive Committee of the Chinese Soviet Republic in Shazhouba Village. In April 1933, after Mao Zedong moved to Shazhouba from Yeping with the provisional central government, he found that it was very difficult for the people here to drink water. In order to prevent the people from drinking dirty pond water for a long time, Mao Zedong personally conducted on-site surveys and investigations of underground water sources. In September One day, he led cadres, Red Army officers and soldiers, and local people to open the well.
