What did the "discovered books" of confucius do for wang mang?

Wang Mang hoped to gather support from the peasantry be introducing reforms. Wang Mang announced the discovery of books written by Confucius, which were supposedly discovered after Confucius’ house, was destroyed more than two hundred years ago. The discovered work supported the same kind of reform that Wang Mang sought.

Wang Mang defended his policies by quoting from the discovered books. Following what was portrayed as Confucian scripture; he decreed a return to the golden times when every man had his measure of land to till, land that in principle belonged to the state. He declared that a family of less than eight that had more than fifteen acres was obligated to distribute the excess amount of land to those who had none.
