Yeah, it really works. My son happened to watch many students practice this and was eager to buy it. At first, he thought his son was playful and wanted to practice. Now, we misunderstood him! Warm hands and feet, less chronic cough, these can be felt in 2 to 3 weeks, sports performance can be felt in 2 to 3 months, and learning becomes conscious and focused. When my son bought it, I also asked the teacher. The teacher said that many children in the school are practicing, which is developed and produced by regular manufacturers. They are pioneers in the field of robot-assisted sports, winning prizes in national invention competitions, owning papers, patents, trademarks, copyrights and so on. They exercise their concentration, balance, flexibility and agility by using intelligent hardware and life science and technology based on the principles of space training and Tai Chi pushing hands, so as to improve their relaxation, practice and fitness. You can check it online. Now that I think about it, it's a good thing to start practicing early, otherwise other students' grades will improve, and if their children don't practice, won't they be behind the times?
