Li Bai， the famous poet of the Tang Dynasty， once dreamt of riding the wind to a sacred mountain in the sea. The mountain was shrouded with the cloud and crawling with flowers and trees. Li bai was mesmerized by the beautiful scenes. Then， a huge brush rose from the sea and penetrated into the clouds just like a jade pillar. Li Bai thought， if I can get the huge brush， and use the land as the inkstone and the seawater as the ink， I can write poems about all the wonderful scenes of the world. It is definitely a good thing.”
　　When he was thinking， the tip of the brush suddenly displays lights of five colors and then a red flower blossomed on the tip of the brush. Li Bai was stunned by the scene. However， when he reached out to touch the flower， he suddenly woke up. He felt a great pity and decided to visit every part of China to find the brush in his dream. When he arrived at the Yellow Mountain， he found the brush-like mountain with a flower-shaped top and was amazed to say that the brush in his dream was there.
　　People also said that Li Bai could write wonderful poems after that dream.
