The powerful French emperor Napoleon I made a comeback after being defeated by the European anti-French Coalition forces in 18 14. In 18 15, he organized 300,000 troops to attack the European anti-French Coalition forces, and the result was disastrous in Waterloo. On June 22, Napoleon was forced to abdicate, and was soon escorted by the British army to the remote Atlantic island of St. Helena and imprisoned. In the third year of imprisonment, Amish came back from China in frustration. On his way home, he happened to pass by St. Helena. When Amish heard that the world-famous Napoleon I was imprisoned here, he wanted to meet him and listen to the legendary figure's views on China. With the consent of the governor of the island, Amish people met with the former emperor. Amish talked about his experience in China and thought that only by knocking on the door of China through war can the autocratic rulers of China understand that opening the door is beneficial to both sides. At that time, Napoleon was full of contempt for British practices. He commented on Britain's idea of solving problems by war: "Fighting this huge and rich empire is the biggest stupid thing in the world." He went on to say, "You may succeed at first. You will seize their ships and destroy their military and commercial facilities, but you will also let them know their own strength. They will think; They will build ships and equip them with artillery. They will invite gunmen from France, the United States and even London to form a fleet and defeat you. " Amish retorted, "China is a powerful giant with clay feet behind its surface. It is very weak." But Napoleon thought that China was not weak, but a sleeping lion. "From today's point of view, the lion is asleep, and even flies dare to fall on its face and scream." Napoleon went on to say, "Once China wakes up, the world will shake." After this sentence was uttered from Napoleon's mouth, it had a strong sensational effect. "A Sleeping Lion-China" quickly spread throughout Europe and the world.

Europe's understanding of China and the East began as early as Genghis Khan's Western Expedition. At that time, Europe called orientals the "yellow peril". Then The Travels of Marco Polo introduced the prosperity and strength of China in detail. Napoleon could not have been ignorant of China.
