Skill and appearance in Tai Chi

You can copy the looks, but you can’t copy the skill.Chen Yingjun

Chen Yingjun said that to me once, when i did a rather good copy of a Taijiquan (Tai Chi) move in Laojia Yilu. What it means is that it is easy to copy the outside appearence of a Taijiquan (Tai Chi) posture, but it is impossible to copy the Gongfu. Skill must be earned and honed by practice, and refined by the understanding of internal movement that dedicated practice fosters.
Copying the looks is surely the first step, but it is only the first.
