In the three years of Qing Xianfeng, the Taiping Heavenly Kingdom was in Nanjing, and the Qing court was shocked. The Qing courts did their best to clearly clear the Taiping Army. The war of Jianghuai continued, the two Huai salt fields in the Qing court's largest salt production area were deserted and the salt road was blocked. The salt tax of the important tax sources of the court was completely free. The disaster is not alone. Huaiyan's "film is not cited". It has always been trapped by salt shortages in 250 states and counties and surrounding areas of six provinces in the middle and lower reaches of the Huaiyan supply area. In order to relieve the suffering of hundreds of millions of people in Chushi, and increased the court's taxes to fill the army, Emperor Xianfeng was forced to order: Sichuan salt to help Chu. For a while, the Sichuan -south businessmen gathered together, and people scrambled to get up and have a dream of getting rich.
