Crazy. Asking about Song Renzong's resume. In his later years, Song Renzong's work pressure was increasing, and his spirit became more and more unstable. I was intrigued every day, and finally I had a big mental problem. Later, he often said stupid things, and the scene was bleak at night. This is crazy. Song Renzong (10/0 May 30-/kloc-0 April 30, 063), formerly known as Zhao Deyi, was the fourth emperor of the Song Dynasty.
