Yijinjing, Wuqinxi, and Baduanjin are regarded as the three major systems of Tai Chi regimen. “Yi” means the way of yin-yang change and “jin” means tendons and meridians of the human body. Put together, “yi” and “jin” refer to the technique of employing movement and stillness with the aim to improve breathing and mental concentration and strengthen tendons and meridians.

Involving a large amount of activity and difficult movements, Yijinjing is generally appropriate for young adults in good physical condition. For people in poor physical condition or suffering from chronic illness, exercise of single movements can help improve physique and remove illness. Because it may take years to have mastery of Yijinjing, few people practice the original version, and a popular version is Yijinjing – 12 Forms, adapted by Pan Wei of the Qing dynasty.

Featuring a strong sense of Qi, the coordination of breath and mind, the tempering of force with grace, the integration of empty and solid movements, and the combination of movement and quietness, Yijinjing – 12 Forms is a fitness technique able to resist evils and heal illness, prolong life and develop the potential. It is advisable to practice the 12 forms in a consistent way, paying attention to regulating the mind and heart. One to two times of exercise a day are recommended.
