There are many people who teach boxing in the Temple of Heaven, but if you want to learn it, you should find someone who has real kung fu. If you practice on an empty shelf, it will waste time and have no effect. I don't think I can stick to it after practicing for a while. I recommend a 20-generation descendant of Chen Taiji to teach in Beijing, but I forgot the website. You search "Beijing Branch of Chen Xin Tai Ji Chuan Research and Promotion Center" on the Internet.
