If you are positive, you can practice Ba Duan Jin or Wu Qin Opera, which is relatively simple and can be learned quickly in front of online videos. If you do static exercises, you can choose "running in unison" or "round pile". There are words and videos on the internet, which is a relatively safe fitness exercise, easy to learn and can be mastered by yourself.

If you are interested in Taoist Qigong, you can search for Chen Ming+Gong Jing or Tian Chengyang+Gong Jing on the Internet. The former is the chairman of the National Taoist Association after liberation, and the latter is the secretary of the Academic Affairs Office of the National Taoist Association. Gong Jing should be the achievement of orthodox Taoism.
