@dadup I would highly recommend looking into Falun Gong aka Falun Dafa as a form of traditional Chinese Qigong but in my opionion it is far more advanced than what is currently out there in the public. In terms of a teacher/master to guide you, Master Li Hongzhi has placed all his teachings in easily accessbile books, audio lectures and exercise videos which are all free to access at www.falundafa.org. I wish you all the best. Please feel free to contact me if you require any assistance I am sure you will find this very fulfilling and exactly what you are looking for! :)
