Did the historical figure Tao Xingzhi study Xing or Hang?

He read "Xing" because he named it himself. Tao Xingzhi changed his name three times in his life. His parents named him Tao Wenjun. When he was 19 years old, he was deeply influenced by Wang Yangming's theory of "unity of knowledge and action" in college, so he changed his name to "Tao Zhixing", thinking that "knowing is the beginning of action" and knowing precedes action. But soon, he realized the idealism, so he flipped through Wang Yangming's theory and put forward that "doing is the beginning of knowing", and only practice can know it. At the age of 43, I renamed myself "Tao Xingzhi". But Tao Xingzhi soon realized that "from action to understanding" is only the first stage of understanding, and then from realizing that action is the higher stage of understanding. He once wrote a poem: Action is Laozi, knowledge is his son, and creation is his grandson. This is his "action-knowledge-action" theory. In order to embody this idea in his name, he also created a word. This word, like "knowing" and "knowing and doing", means "knowing and doing are one".
