For the last stick, editions disagree. The mainland lists give The Three Teachings Debate the Way. In the sixth century Emperor Wu of the Northern Zhou summoned spokesmen of Buddhism, Confucianism and Daoism to his court, in a series of formal debates, to argue which teaching stood highest and rank them. The quarrel produced rankings and decrees but no settled answer, and the three traditions lived on side by side in ordinary Chinese life, where many still say the three spring from one source. Another edition gives instead Emperor Xuanzong of Tang dreaming his way to the palace of the moon. The debate story fits this lower stick's warning well: argue a sacred question in circles, and you come out more confused than when you began.
