They often tool skills as examples to expound their respective thought, to make use of objects for giving explicit instructions and to reason things out with implements. It is indeed something rare and deserving praise for the Kao Gong Ji, the earliest monograph on handicrafts at that time, to sum up the scientific experiences of various kinds of workmanship and put forward the simple and straightforward handicraft viewpoint.

The handicraft articles made in various states all reflected the strong flavor of their respective style.
