He carved Wood and served his Parents
During the Han dynasty lived Ting Lan, whose parents both died when he was young, before he could obey and support them; and he reflected that for all the trouble and anxiety he had caused them, no recompense had yet been given. He then carved wooden images of his parents, and served them as if they had been alive. For a long time his wife would not reverence them; and one day, taking a bodkin, she pricked their fingers in derision.
