The cradle of the Red Revolution - a trip to Ruijin Hongjing in Jiangxi. The red well is a well excavated by the military and civilians led by Comrade Mao Zedong, chairman of the Provisional Central Government during the Soviet period, next to the village of Shazhouba. To this day, this moving story is still widely celebrated here. In April 1933, after Chairman Mao came to Shazhouba, he found that the masses of Shazhouba were drinking pond water after work, and he took the interests of the masses to heart, and after some investigation, he made up his mind to solve the problem of drinking water for the masses. Chairman Mao's practical actions have set an example for the people. Since then, the people of Shazhouba have ended the history of drinking dirty pond water.
