Zhao Gou (1107-1187), Emperor Gaozong of Song Dynasty, also named Deji, was the ninth son of Zhao Ji, Emperor Huizong of Song Dynasty, and the younger brother of Zhao Huan, Emperor Qinzong of Song Dynasty. He was named King Kang at the age of 15. In November of the first year of Jingkang in the Northern Song Dynasty (1126), the Jin soldiers captured Bianjing (now Kaifeng, Henan), the capital of the Song Dynasty. Emperors Hui and Qin were made prisoners, and the Northern Song Dynasty was destroyed. At that time, Kang Wang Zhao Gouzheng was appointed as the general marshal of the Hebei army, with tens of thousands of troops outside. The old generals of the Song Dynasty supported him as emperor. On the first day of May in the following year (1127), the 21-year-old Kang Wang Gou officially ascended the throne in Yingtian Mansion (Shangqiu, Henan, then called Nanjing). He changed the Yuan Dynasty to Jianyan, which was known as the Southern Song Dynasty in history, and Gou became Gaozong. He was the first emperor of the Southern Song Dynasty. In the early years after Zhao Gou came to the throne, he was still able to appoint some anti-war generals. But he was not trying to move north to regain the Central Plains, but wanted to please the Jin people. After moving south, he established his capital in Lin'an (today's Hangzhou, Zhejiang). When he was in power, he "regarded Hangzhou as Bianzhou". He only paid tribute to the Jin Dynasty and declared himself a minister, and lived in peace for thirty-six years.

Zhao Gou was politically incompetent, but he was good at calligraphy. He was good at Zhen, Xing and Cursive. God can create wonderful things wherever he can." His calligraphy influenced and influenced the southern calligraphy world, and many later generations imitated his calligraphy.

Zhao Gouchao was obsessed with calligraphy. Lu You once said: "Si Ling mastered the Eight Dharma, paid attention to the ancient elegance, visited famous Dharma books and paintings, and spared no effort. In his spare time, Yan spent a lot of time playing, copying and copying." He once said to himself: " Since the Wei and Jin Dynasties and the Six Dynasties, I have copied all the writing methods. I have prepared all the styles in the pen, and the conciseness of the meaning is still a matter of choice. When it comes to Ruohu's calligraphy, the testing becomes deeper and the drawing becomes stricter, and it becomes a chant." He compiled and collected Xuanhe. The famous paintings of the Zhan Dynasty, which were lost due to the war in the imperial court, actively promoted the public to study calligraphy. He believed: "If scholars are less diligent in calligraphy, then dot painting will have its place. There is no shame in doing it in front of the wall." He was good at learning (Lanting Preface), so he gave it to the princes and ministers of the court. He also asked Song Xiaozong to learn calligraphy. For a time, with Gaozong as the center, there was almost a climax of calligraphy learning in the Southern Song Dynasty. Ma Zonghuo said in "Shu Lin Zao Jian": "Gaozong first learned the character Huang. The world's Xiran learned the character Huang, and later made the character Mi. The world's Xiran learned the character Mi, and finally made the character Sun Guoting, and the character Sun was prosperous... ...It is because of a small skill that only advocates it from the top, and its popularity is like this." This kind of artificial influence on the rise and fall of calligraphy style based on the likes and dislikes of powerful people affected the development of calligraphy in the Southern Song Dynasty, but Song Gaozong's contribution to the calligraphy world of the Southern Song Dynasty was still insignificant. obliterated.

He is the author of a volume of "Han Mo Zhi", and his handed down ink writings include "Cursive Script Luo Shen Fu", "Zhengcao Thousand Character Essay" and "Guangming Pagoda Stele", etc. The biographical versions of "Gu Kai's Daughter's History of Admonitions and Inscriptions" and "Chu Suiliang and Ni Kuan's Praise" are also said to have been written by Gou.
