Why was Han Yu the leader of the Eight Masters in Tang and Song Dynasties instead of Su Shi?

Han Yu is a character with strong aura and presence. As a literary leader, he "holds the handle of literature and looks up to the world" and "has been famous for more than 30 years" (Liu Yuxi's "Sacrifice to Korean Officials"); As a writer, he dares to be the first, majestic, and writes poetry for the text; As an individual "person", he is upright and brave, with a great personality and a sincere husband. Such a man is married, but he is also a man with temperament. He is not only sensitive, but also sensitive to many subtle pleasures or troubles in life, and has a humorous side. -Pan-Li Xiang

Han Yu is indeed a rare historical talent, and his influence dwarfs countless emperors. On the political stage in the mid-Tang Dynasty, he played the roles of supervising the imperial censor, taking exams, learning the imperial edict from doctors, serving as assistant minister of punishments, making a toast to imperial academy, and serving as assistant minister of official departments. I have made great achievements wherever I go. But his main contribution is in literature. He is an advocate of the ancient prose movement, advocating inheriting the prose tradition of the pre-Qin and Han dynasties, and opposing the parallel prose that pays attention to the antithesis of melody and ignores the content. Wei Wen was honored as the first of the "Eight Masters in Tang and Song Dynasties" because of his majestic, thorough reasoning and strong logic. In terms of feudal ideology and morality, he is also unique, resolutely opposing Buddhism and rejecting Taoism, vigorously advocating Confucianism, and advocating the inheritance of Confucian orthodoxy, which is the forerunner of Neo-Confucianism in Song and Ming Dynasties. Therefore, Su Shi, a Song Dynasty man, highly praised him, saying that he had a great achievement of "decline after eight generations, and his Tao was weaker than the world".
