I think octupole depends on the power of opening and closing, which is symmetrical. The opening and closing of the octupole is that the left hand and the right hand can be folded in the opposite direction at the same time. Compared with Tai Chi, Tai Chi means that all eight limbs turn in one direction, with the left hand outward and the right hand inward, asymmetrical and bipolar. Some people say eight knots, head and hips+shoulders, elbows and hands+hips, knees and ankles. This statement is not accurate because it is not unique to octupole. Every fist says that. You asked Tai Chi, and he also said that people who can play eight knots should be strong. You asked Xingyiquan and Wing Chun, and he said the same. Therefore, eight festivals are not unique to octupole, but all martial arts should pay attention to it.
A little advice for boxers who love Bajiquan: Don't rush to exert your strength, don't stamp your feet, and practice yourself carefully. You'd better find a master to follow you, so that the mistakes can be corrected quickly and there will be no problem. Boxing is unintentional, and unintentional is true!
