Zhang Gao
Zhang Gao , courtesy name Congzhou, formally the Duke of Pingyuan, was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Suzong. He was known for his blunt suggestions, which eventually led to his removal as chancellor.
Background
It is not known when Zhang Gao was born, but it is known that his family was from Bo Prefecture. His great-grandfather Zhang Shanjian, grandfather Zhang Wuding, and father Zhang Zhigu all served as prefectural-level officials. Zhang Gao himself was said to be handsome and ambitious, and he often conversed about the affairs of the military and statecraft. He was also said to have studied the Confucian classics, but was also devoted to fishing and hunting. In his youth, he studied under the Tang Dynasty scholar and official Wu Jing, and Wu respected him. Later, when Zhang Gao travelled to the Tang capital Chang'an, he lived in a solitary room and did not associate much with others. However, he liked to drink and played the Guqin. If honored men at court invited him to feasts, he would go for the sole purpose of getting drunk.Toward the end of Tianbao era of Emperor Xuanzong, the chancellor Yang Guozhong wanted to retain talented men on his staff. He summoned Zhang and, after meeting him, recommended Zhang to be Zuo Shiyi, a low-level official at the examination bureau of government. After the general An Lushan rebelled in 755 and established his own state of Yan, Yang often consulted Zhang on military matters, and it was at the recommendation of Zhang and another consultant, Xiao Xin, that Yang made another official, Lai Tian, a general, and Lai enjoyed some successes against Yan forces. In summer 756, Yan forces approached Chang'an, forcing Emperor Xuanzong to flee toward Chengdu. Zhang followed Emperor Xuanzong on foot to Chengdu.
During Emperor Suzong's reign
Emperor Xuanzong's son and crown prince Li Heng, however, did not follow him to Chengdu but fled to Lingwu instead, where he was declared emperor. When the news reached Emperor Xuanzong, he recognized Emperor Suzong as emperor and took the title of Taishang Huang. He sent a number of officials, including Zhang Gao, to attend to Emperor Suzong, and in 757, Zhang reached Emperor Suzong's makeshift court at Fengxiang. As Emperor Suzong was impressed by Zhang's suggestions, he made Zhang Jianyi Daifu, a consultant at the examination bureau. He soon further promoted Zhang to be Zhongshu Shilang, the deputy head of the legislative bureau and gave him the designation Tong Zhongshu Menxia Pingzhangshi, making him a chancellor de facto. At that time, Emperor Suzong retained several hundred Buddhist monks to recite sutras day and night, hoping to draw divine favor, and their voices carried within and without the makeshift palace. Zhang, wanting to end the practice, spoke to Emperor Suzong:Emperor Suzong was said to agree with his words, but historical accounts did not indicate whether the practice stopped. Meanwhile, as Emperor Suzong believed Zhang to be capable in both civilian and military matters, he soon made Zhang the military governor of Henan Circuit and commander of the forces in the region, replacing Helan Jinming. Zhang knew that, at that time, the general Zhang Xun and the city that he was defending, Suiyang, were under heavy siege, and he therefore tried to march his troops at twice the speed to try to save Suiyang. He also ordered the generals in the region to report to Suiyang to try to save it, but by the time that he arrived in the locale, Suiyang had already fallen, and Zhang Xun was killed by the Yan general Yin Ziqi. In anger, Zhang Gao summoned one of the generals who had disobeyed his order and who had refused to try to save Suiyang, Luqiu Xiao and executed Luqiu by caning. Subsequently, after a joint Tang and Huige force recaptured the Tang eastern capital Luoyang, Zhang and five military governors under his command, Lu Jiong, Lai Tian, Li Zhi the Prince of Wu, Li Siye, and Li Huan, recaptured the commanderies throughout the Henan and Hedong region, except for two commanderies where the Yan generals Neng Yuanhao and Gao Xiuyan held out. He was created the Duke of Nanyang.
Meanwhile, Tang forces were putting An Lushan's son and successor An Qingxu under siege at Yecheng, and with the siege proceeding and the last major remaining Yan general, Shi Siming, submitting his post of Fanyang to Tang, it appeared that the realm would be soon peaceful. However, Zhang distrusted Shi, believing that Shi was merely buying time and would soon rebel himself; he thus advised Emperor Suzong to use extreme caution with regard to Shi. He also distrusted another Tang general, Xu Shuji and suggested that Emperor Suzong recall Xu to the capital. However, Emperor Suzong trusted the reports of eunuchs he sent to meet with Shi and Xu, which stated that both Shi and Xu were trustworthy. In spring 758, Emperor Suzong thus removed Zhang from his posts as chancellor and military governor, instead sending him to Jing Prefecture to serve as its defender. Zhang was soon recalled to serve on the staff of Emperor Suzong's crown prince Li Yu and Zuo Sanqi Changshi, a high-level advisor at the examination bureau. In 761, however, after a plot to make Emperor Suzong's cousin Li Zhen the Prince of Qi emperor was discovered, as Zhang had previously purchased a mansion from Li Zhen, he was considered Li Zhen's associate. Emperor Suzong thus exiled him to Chen Prefecture to serve as the census officer.
During Emperor Daizong's reign
Emperor Suzong died in 762, and Li Yu succeeded him. Emperor Daizong pardoned many officials who had been punished during Emperor Suzong's reign, and he made Zhang Gao the prefect of Fu Prefecture. He soon made Zhang the prefect of Hong Prefecture as well as the commander of the forces in the seven prefectures around Hong Prefecture. He also created Zhang the Duke of Pingyuan. Subsequently, when forces under the agrarian rebel Yuan Chao were disturbing the region, Zhang led his own forces at Shangrao and defeated Yuan's forces, killing several thousand. He also killed two other significant agrarian rebels, Yang Zhao and Shen Qianzai. Zhang was thereafter made the governor of Jiangnan West Circuit. He died in 764.It was said that, despite Zhang's meteoric rise—becoming chancellor within three years of being a civilian—he was respected for his honesty and humility, as well as his willingness to open himself to his subordinates and good insight. Therefore, despite his lack of seniority, he was respected as any other senior official.
