Based on this paragraph about the Ming treasure voyages, who commanded the fleet?

Context: The Ming treasure voyages were the seven maritime expeditions undertaken by Ming China's treasure fleet between 1405 and 1433. The Yongle Emperor ordered the construction of the treasure fleet in 1403. The grand project resulted in far-reaching ocean voyages to the coastal territories and islands in and around the South China Sea, the Indian Ocean, and beyond. Admiral Zheng He was commissioned to command the treasure fleet for the expeditions. Six of the voyages occurred during the Yongle reign, while the seventh voyage occurred during the Xuande reign. The first three voyages reached up to Calicut on India's Malabar Coast, while the fourth voyage went as far as Hormuz in the Persian Gulf. In the last three voyages, the fleet traveled up to the Arabian Peninsula and East Africa.
