In 3, another major event happened that greatly increased Wang Mang's power. Wang Mang's son Wang Yu (王宇), dissatisfied with his father's dictatorial rule, conspired with Emperor Ping's maternal uncles, the Weis, against Wang Mang. When their conspiracy was discovered, Wang Mang had not only Wang Yu and the Weis (except Consort Wei) put to death, but also used this opportunity to accuse many actual or potential political enemies as being part of the conspiracy and to execute or exile them. This included even his own uncle Wang Li (王立), whom he forced to commit suicide by forging an edict from Grand Empress Dowager Wang, from whom he hid the truth (and instead told that Wang Li had died of an illness). Wang Mang made Grand Empress Dowager Wang feel as if she were in control of the situation, however, by arranging for her to periodically survey the areas around the capital Chang'an to reward people with money and goods and to visit orphans and widows. He also ingratiated himself to her by building an impressive temple for her husband Emperor Yuan.
