Han Yu Meets the Snow is the story every edition attaches here. Han Yu, the great Tang essayist, protested in 819 when the emperor welcomed a relic of the Buddha into the palace, and was exiled to Chaozhou on the far southern coast. On the road through the Qinling mountains a snowstorm buried the way at Lan Pass, his horse could go no farther, and there was no one in sight. Then his nephew Han Xiangzi, later counted among the Eight Immortals, came through the snow to meet him. Years earlier Xiangzi had shown him a couplet he could not understand: clouds across the Qinling, snow blocking Lan Pass. Now he did. It suits a middle stick of fog on the road and a guide who appears: the worst moment was also the turning one.
