In the 500 years of the Forbidden City, the fire burned more than ten times and was shelled once. No one dares to pull out the arrow on it.

The Ming dynasty was originally the fief of Judy, the prince of Yan. After the war in Jingnan, some ministers suggested that the emperor should follow the example of Zhu Yuanzhang, the Ming emperor, and take Fengyang as the capital. At the same time, he ordered the rich people in Jiangnan and other places and the refugees from all over the country to move here. In the fourth year of Yongle, he ordered to build a palace for himself according to the model of Nanjing palace, and sent people to collect wood and stones all over the country, not to mention how many years it took craftsmen to collect raw materials and other preparatory work.

Most of the nanmu trees that built the Forbidden City grow in the mountains. People cut down trees day and night at the risk of their lives. Many people were either exhausted or accidentally fell off a cliff, so later generations left a helpless joke? A thousand goes into the mountains, and 500 goes out? Used to describe the difficulty of wood mining, and stones used for construction are equally difficult. The largest single stone behind Baohe Hall was mined in Fangshan in the southwest. This is how the history books record the scene of transportation at that time. Thousands of workers dig a well every mile on both sides of the road. In the cold winter, they take water from the well. Because the temperature is enough, the road instantly becomes an ice road. This method can only be used at night or during the day.

In the eighteenth year of Yongle, the palace was built and a fire broke out the following year. The first three halls were burned down, and the three halls were rebuilt and the Qing palace was cleaned in five years. Until the thirty-sixth year of Jiajing, a fire broke out in the Forbidden City, and Fengtianmen, Wuwenlou and Wumen were destroyed by the fire. It was not completed until Jiajing was forty years old. In the twenty-fifth year of Wanli, the first three halls and the last three halls were completely destroyed by fire in the Forbidden City. It is 1628 after repair.

In the seventeenth year of Chongzhen, 1644, Li Zicheng fell and the Ming Dynasty perished, but it was quickly defeated by the Qing army who entered the customs. When retreating, a big fire hit the Forbidden City again. After the Qing army entered the customs, it took fourteen years to repair the Forbidden City. On July 19 17, warlord Zhang Xun resumed Puyi, and Duan immediately responded. Among them, the teachers and students of the aviation school joined the battle, bombed the Forbidden City by plane, only 300 meters away from the Forbidden City, and dropped three bombs at ultra-low altitude. This bombing is considered to be the first air strike in East Asia.
