The answer to the question of whether the cold-faced king, Emperor Yongzheng, was the most powerful in using political tactics was not very simple. Because in the history of China, Emperor Yongzheng had made many achievements and contributions during his reign, and his political means and political tactics were also relatively famous in history. During the reign of Emperor Yongzheng, he took a series of effective measures to strengthen the central power, rectify the government institutions, strengthen the military management and reform the financial system, which laid the foundation for the later development of the Qing Dynasty. He also increased the income level of farmers and promoted social and economic development through the implementation of the policy of "sharing Ding into Mu". However, there may be some controversy about the answer to the question of whether Emperor Yongzheng was the most powerful in using power. This was because in the history of China, many emperors had outstanding political skills and political means, such as Tang Taizong and Song Taizu. Their means were quite superb. Therefore, whether Emperor Yongzheng used the most powerful political tactics needed to be evaluated according to different historical backgrounds and evaluation standards. However, judging from the policies and measures taken by Emperor Yongzheng during his reign, he was indeed a very capable and talented emperor, who had an important impact on the development of Chinese history.
