Zhang Dian (1035-1105), a native of Pucheng, Fujian. As a politician in the Song Dynasty, the key player in the struggle between the old and new parties was the illegitimate son of Zhang Yu and his nursing mother. Jiayou was admitted to the Jinshi in the second year, but his nephew Zhang Heng won the top prize, so he didn't just go, and then promoted to the Shijia Department and transferred Luo Ling. Although Zhang Dian advocated reform, but because of disagreement with Wang Anshi and only used it for the correction of the Chinese book, and then used it for Song Shenzong, Xining five years, was ordered to visit Jinghu North Road, five years later, he was transferred to the governor's affairs, pacified the rebellion at the junction of Sichuan, Guizhou and Guangxi provinces, and appeased 45 states. After the ups and downs of the eunuch sea, in the Zhezong Dynasty, the power of the government and the opposition leaned, and a large number of old party officials were exiled. After Huizong ascended the throne, he was demoted again and again because of the opposition of Zhang Dan, and died in office soon after. After his death, he was posthumously demoted to the deputy envoy of the Zhaohua Army.

Zhang Dian (1035-1105), a native of Pucheng, Fujian. "The History of the Song Dynasty: The Biography of Zhangdun" said: "He is handsome, erudite and good at writing." "At the beginning of Xining, Wang Anshi Bingzheng, Yue Qicai, used to edit the three divisions of the regulations, add Jixian school, and check the Chinese book." Xuan was ordered to be the Hunan and North Inspection and Defense Envoy, and used martial arts to "promote knowledge and system, and the straight academy sergeant was sentenced to the military superintendent." In May of the seventh year of Xining (1074), he was appointed as the third envoy (counting the phase), and in October of the same year, he proposed to establish an important institution for changing the law - the Accounting Department of the Three Divisions. During this period, he strongly sponsored Wang Anshi's reform of the law and became the backbone of the reform faction. In the eighth year of Xining (1075), Wang Lu exchanged conflicts, Lu Huiqing degraded, and Deng Juan talked about "the traitor of the three envoys Zhang Dian and Huiqing, and he knew Huzhou".

In the third year of Yuanfeng (1080), Shenzong used Zhang Dian as the governor of the government. At that time, Wang Anshi was depressed and retreated to Jinling. The Xining New Deal was basically able to continue in Yuanfeng, and it was inseparable from Zhang Dun, Cai Qu (Yuanfeng's five-year prime minister) and other leaders of the reform faction who insisted on the position of changing the law.

With the turmoil of the political situation, Zhang Dian had several ups and downs in his life, and the "History of the Song Dynasty" actually included him in the "Biography of Traitorous Ministers", and the main "crime" against him was to restore the old law of Xifeng and depose the courtiers of Yuanyou; Unbridled the margins and slandered Xuanren.

Heroic personality, erudite and good at writing. After Zhongjinshi, he was appointed as a county official for the first time, and on the recommendation of Ouyang Xiu, he entered the court for a trial position, was impeached, and returned to serve as a county official.

In the second year of the reign of Emperor Shenzong of the Song Dynasty (1069), Wang Anshi Bingzheng, appreciating the talent of Zhangdun, was used as the official of the three departments to assist in the implementation of the new law. In the fifth year of Xining (1072), Zhang Dian was ordered to visit Jinghu North Road, and after more than three years of barbarian affairs, he opened up hundreds of miles of territory. Subsequently, he successively served as an official of the imperial court and prefectures and counties.

Song Zhezong ascended the throne and moved to the Privy Council. At that time, the Empress Dowager Xuanren was in power, and Sima Guang and Lu Gong were in charge, and the new law was abolished. In the eighth year of Yuan You (1093), Song Zhezong was pro-government, with Shao Shu Xining and Yuanfeng as his ambition, and changed Yuan to Shaosheng next year, and used Zhang Dian as the left servant of Shangshu and the servant of the door. Zhang Dian was the prime minister, reverted to the new law, took revenge on the ministers of Yuanyou, the living flowed, the dead chased and degraded, and tried to abolish the Empress Dowager Xuanren, because Song Zhezong realized that it was wrong. Although Zhang Dian used excessive methods to deal with the old party and played power together, he was able to avoid using officials to protect his relatives.

Song Hui Zongli, moved Zhang Dian Special Advance, and sealed Shen Guogong, but Zhang Dian tasted against his heir, so he became suspicious, and changed to Han Zhongyan and Zeng Bu as ministers to reconcile the old and new parties. Zhang Dian was expelled for his crimes, and died in the fourth year of Chongning.

Zhang Dian was resourceful and decisive, particularly keen on politics, knew people well, and had high military talents, both civil and military. If the Song Dynasty could accept his advice and not choose King Duan, then there would be no Song Huizong. Zhang Dian was upright, deeply convinced of the new law and Wang Anshi, and was even more loyal to His Majesty Zhezong. As an important minister for the revival of the Zhezong Dynasty, Zhezong and he re-conquered the Western Xia, defeated the fierce enemies who had invaded the northwest border of the Northern Song Dynasty for many years, and recovered many fortresses in Hengshan that were shamelessly ceded by Sima Guang; At the same time, the coffins of conservative henchmen such as Sima Guang and others were opened and whipped, completely suppressing the arrogance of the old faction, and at the same time denouncing many conservative party figures, such as Su Shi and many Han Qi and Wenyanbo faction personnel. He also advocated the liquidation of Empress Dowager Gao, who had stolen the authority of the country in the early stage of Zhezong, but failed to make the trip and fell short, so that Empress Shenzong of Empress Dowager Gao's faction was able to establish herself unharmed and the deceased monarch of the Northern Song Dynasty, Huizong. If the liquidation of the Empress Dowager Gao can be carried out, it will be able to deal a deeper blow to the old party, maintain the new policy of Shenzong and Wang Anshi, and further enhance the country's military strength, so as to maintain the military superiority of the Northern Song Dynasty against foreign races, so that it is possible to avoid the subsequent Jingkang shame, the Song family's southern crossing, and the loss of the country, and then the entire Han nation fell into the hands of foreign races for the first time in the Southern Song Dynasty, when the old party prevailed. Zhang Dian can be the entire Zhezong Dynasty of the Zhongxing famous ministers, later generations because the Southern Song Dynasty is controlled by the old party, so it is insulted and slandered, but standing at the height of history, he is worthy of an upright, can be overweight Northern Song Dynasty famous minister.
