叶公好龙
In the Spring and Autumn Period, there lived in Chu a person named Chu Zhuliang, who addressed himself as Lord Ye.
Its said that this Lord Ye was very fond of dragons. The walls had dragons painted on them. The beams, pillars, doors and the windows were all carved with them. As a result, his love for dragons was spread out. When the real dragon in he**en heard of this Lord Ye, he was deeply moved. He decided to visit Lord Ye to thank him.
You mig then on, people knew that Lord Ye only loved pictures or carvings which look like dragons, not the real thing.
