The essentials of Wu Tai Ji Chuan's thirteen knives

When practicing or using the Thirteen Knives of Wu Tai Chi, the waist is the activity hub. When the knife advances and retreats, the waist and legs follow. Using a knife is like using your hands, up and down, front and back, left and right, and the whole body is consistent. There should be no interruption, especially when the knife is not moved forcibly (for example, the arm turns the knife awkwardly). I'm afraid that my internal strength is blocked in bones and joints because of clumsy exertion, but I can't run outside, so I can't work normally. Such as water and silver inside, apply it to the tip of the knife and collect it to the end. Therefore, the practice of Tai Chi Dao is about 5 kg, that is to say, the Dao weighs 5 kg, which is the smallest number, and it can be increased or decreased to the weight that its own shuttle can adapt to, that is, it will naturally not be too laborious to hold. Therefore, the main reason why I want to use a heavy knife is that the rotation of the heavy knife leads to my own internal strength. Therefore, scholars have no waist and leg strength when practicing Taijiquan.
