First of all, he streamlined the salt administration, cut down redundant staff and replaced a group of salt officials who were in the salt administration. In addition to setting up salt supervision management and purchasing salt in ten major producing areas such as Jiaxing, Hailing, Yancheng, Xinting, Linping, Lanting, Yongjia, Dachang, Houguan and Du Fu, saltworks are also set up in Lianshui, Huzhou, Yuezhou and Hangzhou to facilitate the storage, transportation and marketing of salt. In order to maintain the best-selling of official salt, he also set up inspection institutes in Yangzhou, Chen Xu, Baisha, Huaixi, Zhexi, Songzhou, Sizhou, Zhengzhou and other places 13 to arrest the smuggling and sales of illicit salt and also manage the marketing of official salt. Although Ada's deployment is very thorough, salt merchants are mercenary. Some salt merchants in remote areas are reluctant to go because their profits are too low, so they are short of salt. In order to make up for it, Ada set up Changping Salt Field to transport official salt to remote areas for storage, and then sell it when the demand exceeds the supply, so as to regulate the market and stabilize the salt price. In addition, Ada has established numerous salt depots in wuyue, Yang and Chu, and accumulated more than 20,000 stones as reserves, thus ensuring the needs of the people.
These reforms put salt administration on the road of healthy development, which not only facilitated businessmen, but also stabilized salt prices. And more importantly, it greatly increased the income of the Tang government. The salt profit of Jianghuai increased from 400,000 to 6 million per year, accounting for almost half of the national income.
