Needless to say, it must be Ming Chengzu. Judy's five expeditions to Mongolia and his south expedition to Vietnam opened the greatest maritime era in China's history, that is, the earliest king who paid attention to sea power. Judy moved the capital from Nanjing to Beijing. The Forbidden City was built in Beijing, and the Grand Canal was dredged again to ensure the food supply of the canal. In addition, a large-scale book compilation activity, Yongle Grand Ceremony, was organized, which is the largest encyclopedia in human history. In any dynasty, it was impossible to accomplish such a great feat, but Judy did it alone, except for his personal charm, when the national strength was in full swing in the Ming Dynasty under his rule.
