What the Laozi(老子) seeks is mildness and is the image in the form of a child. As in Daoism, the mildness was thought to be life of Gwonbeop(拳法) even in Taijiquan(太 極拳). The Daojia thinkers regarded RouRuo(柔弱) as an important element that conceives and grows human life. In other words, what is strong and firm was thought to proceed with being gradually dead in reality even if seeming to dominate and control the world. According to this, their major thought is what sees that being flexible and weak grows and dominates all things in the world.
Song(鬆) was emphasized even in Taijiquan(太極拳), which was influenced by Laozi RouRuo(老子 柔弱). As Song(鬆) is what makes a human being’s mind and body soft, it is the secret code(秘典) that will need to be certainly kept in improving Taijiquan(太極 拳). Taijiquan is a kind of martial arts, but stressed mildness and slowness beyond the conventional thought. This can be known to have close relationship with RouRuo(柔弱) that was pursued by the Daojia thinkers.
The Daojia theorists thought that practicing RouRuo(柔弱) in real life can lead to making it smooth for a flow of QiXue(氣血), which is necessary for maintaining a human being’s health. Perfecting the movement of Taijiquan(太極拳), which is Song(鬆) and slow, has the same effect of making it smooth for a flow of QiXue(氣血), which was stressed by the Daojia thinkers. As Song(鬆) is the heart(要諦) of Taijiquan, it is an important element that promotes a human being’s Gongryeok(功力) and health.
