The Kung fu master is the top of their art form. To be a master takes huge dedication, many years of practice, spending every single day investigating every intricate move in great detail until the body instinctively understands how to make the right move in every circumstance. Each move becomes assimilated into the very being of that person such that even if the move was taught to them by someone else, it has now become their own, part of them.
The master never stops training because they know that the other masters will never stop training, trying to better themselves. The master who stopped training 10 years ago is no longer a master. The body’s forgets as well as the mind.
