The picture is derived from the painting stones of the Han Dynasty（202BC-220）. This picture is the images of cars and horses. At that time, the car was the fastest way of transportation. Emperor Wu of the Han Dynasty spent a lot to send troops to the western regions. One of the purposes was to obtain a fast means of transportation, Tianma. At that time, having a car and a horse was a symbol of status. It is said that after Confucius’ beloved apprentice Yan Hui died, his father Yan Lu had no money to buy a coffin. Yan Lu begged Confucius to sell his car to buy a coffin for Yan Hui, but Confucius did not agree, saying that people like him could not go out without a car.
