One day, Lu Sheng went to the capital for the imperial examination On his way when he reached Handan, he stayed at an inn. A Taoist priest surnamed Lii was also staying there. Sitting in his room, Lu Sheng lamented over his poverty and unsuccessful career and sighed in grief with knitted brows and a long face.

As the Taoist priest Lu saw Lu Sheng in such a state, he took out a pillow from his pocket, gave it to him and said:

"Try sleeping with this pillow under your head. It may be good for you."

In the Tang Dynasty, there was a scholar named Lu Sheng.

Lu Sheng went to bed as told, while the owner of the inn was steaming millet. With the Taoist priest's pillow, Lu Sheng fell asleep and had a dream. In his dream, he married the daughter of a high official surnamed Cui in Qinghe and he himself also became an official. He had a brilliant career as an official and often got promoted. Once he went to fight against the enemy and rendered outstanding service. Thus he rose higher and higher in officialdom till he became the Minister of Revenue and concurrently Imperial Law Enforcement Official.

Lu Sheng woke up from his dream and found himself still sleeping at the inn, with the Taoist priest Lu sitting beside him. The millet which the owner of the inn had been steaming was not yet done.

Later, someone was jealous of him and framed a case of conspiracy against him. The emperor ordered to have his house ransacked, his property confiscated, and him condemned. After a few years, the emperor reinstated him to his original post. He had a large family with lots of children and grandchildren, and enjoyed great wealth and high position as before. In his old age, he fell ill, could not be cured, and eventually died.
