I know that Zhang Mei's yoga is not in physical education class, but I happened to find a yoga practice of cervical spine maintenance recorded by a teacher on the Internet when cervical spondylosis was serious. After practice, my cervical spondylosis has been greatly relieved. Before each attack, I can relieve the pain through yoga neck movements. Later, I practiced yoga for four seasons in succession, which was also very good. Teacher Zhang Mei's lecture makes people feel like spring breeze. The gentle voice can easily relax my body and mind, and the arrangement of actions is also very scientific. She is the best yoga teacher I have ever seen.
