Zhang Tianshi's character or Yuan Tiangang's character, which is more severe?

If you ask this question, you play too many games. My answer is Zhang Jiao, who is famous for painting. He is the founder of Taiping Road. Zhang Jiao believed in Huang Lao's theory in his early years, and he also had a deep study of divination, which was very popular in Han Dynasty. He is also familiar with folk medicine and witchcraft. Yuan Tiangang was just an astronomer and astrologer. He is a street vendor and can't draw symbols.
