The more you want to learn Chinese culture and Chinese mandarin well ,the more you need to understand Chinese culture. Let me tell you a traditional Chinese story…
A discontented poor scholar named lu sheng yearned all day long for an official position and a distinguished career. At an inn in Handan, he met a Taoist monk who gave him a porcelain pillow. At the time the inn host just started cooking a pan of millet. Lu fell asleep while waiting for his lunch, and dreamed that he married the daughter of a rich man, succeeded in the highest imperial examination ,become a high-ranking official ,had many children ,and enjoyed a life of wealth and comfort. However, he woke up to find that a pot of millet was still cooking on the fire. The story is meant to satirize the nullity of fantasies and unfeasible hope, giving rise to the phrase  ‘golden dream on the porcelain pillow’.
