Shortly after the Salt and Iron Conference, the liquor monopoly was cancelled, and Sang Hongdan, the person who formulated and implemented this policy, was executed by General Huo Guang. However, the salt and iron monopoly remained unchanged until the end of the Western Han Dynasty. After the Eastern Han Dynasty, the salt and iron monopoly came and went. By the Tang Dynasty, except for the northwest region, the iron monopoly was basically abolished, while the salt and wine monopoly was restored. In the Ming Dynasty, the liquor ban was reopened. After the mid-Tang Dynasty, the tea ban was increased. In the Southern Song Dynasty, in addition to salt, tea and wine, alum, incense, copper, tin and other products also became new specialty products. From now on, salt will be sold exclusively by the government or by government-authorized merchants. In 1931, there were 1,972 salt-selling counties in the country, of which 94 counties adopted the official-to-people sales system or the official sales system, accounting for about 5% of the total; 907 counties adopted the ticket dealer exclusive contract system, accounting for 46 of them. In 1941, at the 8th plenary session of the 5th Central Executive Committee of the Kuomintang, Kong Xiangxi and others' proposal to establish a monopoly on consumer crystals such as salt, sugar, cigarettes, wine, tea, fire purple, etc. was adopted, and was gradually implemented in the future.
