Wang Xizhi is particularly remembered for one of his hobbies – rearing geese. Legend has it that he learned the key of how to turn his wrist while writing by observing how the geese move their necks. It is said that in Shaoxing there was a Daoist monk who had raised a flock of more than ten fine geese. One morning Wang Xizhi decided to take a small boat and go there. He was delighted with the geese and wanted to buy them, but the monk refused to sell. Wang tried in vain to persuade him. Finally, the monk told Wang that he loved Daoist philosophy and had always wanted a transcription of Laozi's Daodejing (道德經) with its commentary by Heshanggong. He had already prepared the silk, but no one was qualified to write it. He asked if Wang would condescend to transcribe two chapters each from the Dao and De sections, for which he would give Wang the whole flock. Wang stayed for half a day to write out the chapters, then he caged the geese and returned home.
Wang Xizhi had seven children, all of whom were notable calligraphers. The most distinguished one was his youngest son, Wang Xianzhi (王獻之). They are commonly referred to as the “Two Wangs.”
