Allegedly Han Xiangzi was the nephew of Han Yu, a Tang Dynasty high official, writer and neo-Confucius who viewed the social success as the highest accomplishment of life, which is quite a departure from the original Convucuism. It is said that Han Xiangzi once attended his uncle's high profile birthday party as a hermit Daoist and showed the guests how to edit the external environment, which was his way to show the world there is something more advanced than mundane achievements. Han Xiangzi is best known for his drought relief deeds for farmers. As legend has it, whenever he played a certain tune on his vertical bamboo flute, the sky would rain. Thus he sands for water in Five Agents and ☵ (坎) in Eight Trigrams.
