Zhu Jiaxun's hard-pen calligraphy is a classic focusing on family style, but only 524 words brilliantly expound the way of self-cultivation and family harmony. It embodies the outstanding features of China traditional culture, such as respecting teachers and valuing morality, managing the family diligently, being kind to neighbors, and so on, which still has practical significance today.
The idea of Zhu Zi's family instructions is mainly to advocate family virtues and family education, and to convey the thoughts and spirit of self-cultivation and family harmony through calligraphy works.
