明仁宗
Already in May 1421, during the reign of the Yongle Emperor, an order was issued for the suspension of Zheng He's maritime expeditions, apparently on account of their cost (although the order apparently did not affect the 6th voyage of Zheng He, staged around that time). Zhu Gaochi, as soon as he was enthroned as the Hongxi Emperor in September 1424, cancelled Zheng He's maritime expeditions permanently, arguably burned down the fleet or left the ships to decompose, and abolished frontier trade of tea for horses as well as missions for gold and pearls to Yunnan and Vietnam. He restored disgraced Confucian officials, such as the Yongle Emperor's minister of revenue Xia Yuanji (imprisoned since 1421), and reorganized the administration to give high ranks to his close advisors. Hanlin academicians became grand secretaries, and they dismantled his father's unpopular militaristic policies to restore civil government. The Hongxi Emperor improved finances by canceling requisitions for lumber, gold, and silver. Taxes were remitted so that vagrant farmers could return home, especially in the overburdened Yangtze River Delta. The Hongxi Emperor appointed a commission to investigate taxes. He overruled his secretaries by ordering that grain should be sent immediately to relieve disaster areas.
