In April 1552, the Jiajing Emperor promoted Xu to the Grand Secretariat. At the time, there were three grand secretaries, with the most influential being Yan Song. Yan tended to find compromise solutions to difficult situations and was often smug and complacent. Xu, on the other hand, was energetic and decisive. The third grand secretary, Li Ben, was not as strong-willed as his colleagues and focused more on routine work. As the closest aides to the Emperor, the secretaries were often pitted against each other, with Xu being used as a counterweight to Yan. Despite being leaders of rival political cliques, they did not openly display their hostility towards each other. Xu respected Yan's superior position and avoided open confrontations, but still managed to secure positions of power for himself. For example, he promoted Nie Bao to the position of minister of war in 1553, followed by another friend, Yang Bo, who served as minister in 1555–1556 and 1558–1566 before becoming minister of personnel. Xu appointed Ouyang De as his successor at the
Ministry of Rites. He also considered Ouyang for the Grand Secretariat, but the latter unexpectedly died in 1554. Despite maintaining a facade of correctness, Xu did not agree with Yan's proposals and actively opposed him. This led to Yan suspecting Xu of being behind the criticism and lawsuits against him, and he even tried to persuade the Emperor to dismiss Xu. One example of factionalism within the Ming government occurred in the spring of 1558. Wu Shilai, the supervising secretary for the Ministry of Justice, accused three members of Yan Song's party—the minister of war, and two high-ranking officials responsible for the defense of Datong—of incompetence and corruption. As a result, they were dismissed and imprisoned. Wu then went on to indict Yan Song and his son Yan Shifan for corruption that had led to the collapse of the northern border defenses. This indictment was supported by two bureau secretaries in the Ministry of Justice. All three of these individuals had connections to Xu Jie. Wu Shilai and one of the secretaries had passed the metropolitan and palace examinations in 1553, when Xu was a member of the examination board. The other secretary was a native of Huating. Yan believed that Xu was behind the accusation and had the three arrested. During interrogation, which was conducted under torture, all three denied any connection to Xu and claimed that they were only concerned with the welfare of the state. It appears that the interrogators did not put much pressure on them, as they were subordinate to Lu Bing, who was Xu's in-law and political ally. In the end, the trio was dismissed from their civil service positions and transferred to the troops guarding the southern border of the empire. In 1557, Xu's son Xu Fan was appointed as prefect of Guangnan in
Yunnan Province. This appointment was likely due to his father's high position, as Xu Jie had been readmitted to the Imperial University six years earlier for the same reason. Xu Fan was also appointed as office manager of one of the chief military commissions. Xu Jie protested that his son, who was only 29 years old at the time, lacked the necessary experience to effectively govern the prefecture. He also argued that he needed his son to manage his household in Beijing so that he could focus on his work. As a compromise, Xu Jie requested a position for his son in Beijing, though it would be a lower one. The Emperor granted this request and appointed Xu Fan as an aide in the Seals Office. Xu utilized his influence to disseminate Wang Yangming's ethical teachings, which emphasized the inherent goodness in individuals and the importance of recognizing and cultivating this goodness. During his time as minister of rites and grand secretary in the 1550s, he organized the
jiangxue debates on Confucian studies, with the goal of promoting personal growth and ethical conduct among participants. These debates were held in the outskirts of Beijing, and sometimes in the city center, and attracted hundreds of students and officials, lasting for several weeks. While officially focused on discussing the correct interpretation of Confucian teachings and the development of one's character, Xu was aware of their potential for political gain and used them to establish connections and a network of like-minded officials who supported his political beliefs. He navigated this carefully, as forming a political faction was illegal under Ming law. His dedication to these debates on Confucian studies ultimately caused a rift between him and two future grand secretaries,
Gao Gong and Zhang Juzheng, who both leaned towards
Legalism and did not share Xu's passion for Confucianism. Xu proved a successful politician. He was known for his cautious approach, but he also had the ability to be flexible and tough when necessary. He thought political decisions should be made through a consensus among senior officials, rather than being dictated by a small group of top dignitaries. He often promoted his political ideas through informal correspondence with officials in different regions, rather than using official channels of communication. This was a unique strategy that set Xu apart from other grand secretaries. Despite not having the authority to give orders, his high position and close relationship with the Emperor gave weight to his recommendations and suggestions, which he often conveyed in a friendly manner. Regional officials could then present his advice as their own proposals, knowing that they would have his support and be well-received by the central government. Additionally, Xu's insider knowledge of events and attitudes within the Beijing authorities was valuable to the recipients of his letters. While he likely used a similar approach with Beijing officials, these interactions were not documented as they were likely oral. One of Xu's main priorities, as well as that of other grand secretaries, was to build a network of allies among the censors who had the power to impeach corrupt and incompetent government officials. In addition to civilian officials, Xu also placed great importance on talented military leaders. He did not hold any prejudice against the military elite, with whom his family had always maintained good relations. Xu's father had arranged for his sister to marry an officer from
Shandong, and Xu Jie himself had married his son to the daughter of a hereditary officer and commander of the Embroidered Uniform Guard, Lu Bing. Xu actively sought out connections with officers, as shown by his trip to Beijing in 1541 with friends from Huating. While there, they engaged in the usual activities of scholars, such as discussing philosophy over good food and drink and visiting famous mountains and Buddhist temples. They also made a stop at the command of the coast guards in
Zhenjiang. The commander even treated them to a duel between his men and a drum made from the skin of an executed pirate. Throughout his political career, Xu considered the search for, promotion of, and protection of capable officers to be an essential element of his security policy. In the 1550s and 1560s, the Beijing area faced security concerns due to ongoing Mongol raids. These raids varied in magnitude and were particularly prevalent in the wider areas of
Datong,
Xuanfu, and
Jizhen. However, the eastern part of Liaodong and the western part of the northern border remained peaceful. The Mongols living opposite the Beijing region demanded the opening of border markets to trade horses and cattle for Chinese goods such as silk, tea, and food. While such markets were already operating in the west and east, the Emperor refused to allow them in this region. This was partly to avoid appearing weak by complying with the Mongol demand, and also because there were many Chinese refugees and emigrants living among the Mongols. Opening the border would only increase the attractiveness of the Mongolian steppes for dissatisfied Ming subjects. Xu, a supporter of the Emperor, shared this stance. In response to Ming China's refusal, the Mongols launched repeated raids. As a result, Xu spent a significant amount of time defending the Beijing region. He played a key role in organizing the recruitment and training of soldiers, selecting commanders, and coordinating supplies. He also worked closely with the ministries of war, personnel, and revenue to develop an effective defense strategy. Xu's approach towards the Mongol invaders (and the coastal pirates in the south) was guided by four principles. Firstly, he viewed the invaders as wild anarchic bands rather than representatives of a proper state. Secondly, he believed it was crucial to not cede any territory or meet their demands. Instead, the focus should be on properly organizing the defense of border areas. Lastly, any agreements could only be made if the Ming government had control over the situation and could ensure their fulfillment. The security of the Beijing region was a major point of disagreement between Xu Jie and Yan Song. Yan suggested abandoning Datong and Xuanfu and moving the defenses closer to Beijing, while also opening border markets. He believed that the Ming armies were no match for the Mongol cavalry and should wait on the city walls until the raiders had finished plundering and returned home. The Emperor expected his generals to respond aggressively to the raids, and those who followed Yan's approach often faced punishment. Yan faced criticism as well, but he convinced the Emperor that it was merely politically motivated. On the other hand, Xu firmly opposed surrendering any territory to the enemy, but he did not have a solution to the conflict. The situation only improved with the opening of border markets and the negotiation of a peace treaty with the Mongols in 1571, after the death of the Jiajing Emperor in 1567, the resignation of Xu Jie in 1568, and the rise of a new generation of politicians, particularly Gao Gong and Zhang Juzheng. In the 1550s, Xu played a crucial role in the fight against the
Wokou pirates. He focused on maintaining order in the
Southern Metropolitan Area, particularly in the prefectures of
Suzhou and
Songjiang, which were significant sources of tax revenue. As a result, he addressed various issues such as tax arrears, poor population and land registers, problems with tax calculations and distribution, and corruption in the region. These were all matters of national importance. Additionally, Xu advocated for the transition from in-kind taxes to silver. He shared his powers with Yan Song, who oversaw the struggle against the
Wokou and the situation in Zhejiang and Fujian through his adopted son and close aide
Zhao Wenhua and the supreme commander of the three coastal provinces,
Hu Zongxian. While Hu Zongxian's authority technically extended to the Southern Metropolitan Area, Xu still communicated with officials in Nanjing and managed affairs in the region. He paid particular attention to Songjiang Prefecture, which included his home county of Huating. Unusually for a grand secretary, he even maintained written correspondence with prefects and county magistrates despite their low rank. ==Senior Grand Secretary==
