Yang Shi taijiquan striking technique demo
Some points on striking and fajin in Taijiquan - Forms are a very important aspect of Taiji training, but the forms are just one element among many in a complete Taijiquan training repertoire. There are many solo drills as well as partner drills and exercises that round out a complete training regimen. The movements contained within the form help to teach the practitioner the correct body mechanics for striking, joint locks/breaks, and throws/take-downs. Regarding striking, it is my opinion a Taijiquan practitioner should understand that you can not simply punch or kick in the air and expect to be able to learn how to generate power, deliver power, and deal with the rebounding force at impact. You must hit something to develop these skills. I believe your training partner should not suffer the consequences of that skill development, so that is what the bags and pads are for.
Some important qualities to note... Although the stances are quite low (large frame) notice the centered-ness of his body between the feet. The back is stretched with natural curvature and very slight forward bow for balance and to create strength and stability in the connection between all three body structures. Correct knee/foot alignment in both legs. Roundness and fullness of arm positions and leg positions. Elbows and shoulders sinking. Neck stretched and head up. Clear focus and alignment of structures to intended target. Seated wrists.

Slowly to develop body mechanics and then express the power.
