Does anyone know about Teacher Jiang Zongkun’s innate qigong?

Teacher Jiang Zongkun, female, from Yantai, Shandong, 1911--1992, died at the age of 81. She is an old Chinese medicine doctor and the founder of Xiantian Qigong. She learned and practiced a kind of family Qigong since she was a child, and later practiced it on her own After many years of practice, I realized the principles of Xiantian Qigong. I began to practice Qigong using the simplest natural meditation method suitable for modern people. It advocates: not guarding, not guiding, and entering into silence naturally. What is practiced is Xiantian Qi (vital energy), and the method is Natural. Based on virtue. Practice one's nature and transform one's life. Emphasis: Sit quietly and practice one's energy, gain clarity and reflect on mistakes, cultivate one's nature and cultivate virtue!
