Calligraphy and Art
Calligraphy and art is an important part of Wu Gong. Though to many it might be a stretch to see a connection, a common example is that a brush can be trained as a sword. In the movie "Hero", one of the calligraphers (and also a wanted assassin by the emperor) "Broken Sword", was both an excellent calligrapher and swordsman.
This calligraphy was written by Song Dynasty Emperor Hui Zong, a well known calligrapher and Emperor.
Art can be colorful and it can be very simple with just paper and ink. It shows a basic concept of Yin/yang relationship that one can see nature.
