There are few surviving examples of cursive script by Tung. Judging from his seal impressed on this work, it was done at around the age of 60. The style mostly follows that of the T'ang calligrapher Huai-su. The forms of the characters, the thickness of the strokes, and the movement of the brush all reveal more variety than in his earlier style. Much of this work was also done using centered brushwork. With the dry ink applied with speed, the strokes often break up into "flying white"for a light and airy touch that reveals the paper underneath.
