Beijing, called Dadu in Yuan Dynasty; In the early Ming Dynasty, Zhu Yuanzhang established Nanjing (formerly known as Yingtianfu) and called it Beiping. Later, the Ming Emperor Judy launched the "Battle of Jingnan", captured Nanjing, abolished Wen Jian and ascended the throne. In the first month of the first year of Yongle (1403), it was decided to change Beiping to Beijing, build its capital and move the city to the capital. In the fourth year of Yongle (1406), the imperial edict was officially issued, announcing that Beijing would be built the following year. In the 18th year of Yongle (1420), the capital construction was basically completed. The following year, Ming Chengzu proclaimed himself emperor in Beijing. In the seventeenth year of Chongzhen (1644), the Qing soldiers entered the customs and entered the Central Plains, making Beijing the capital of the Qing Dynasty. Moreover, in the Ming Dynasty, the city of Beijing and the palace halls were almost intact, but the building name and some details were changed. The Xinhai Revolution of 19 1 1 overthrew the Manchu dynasty and established the Republic of China without much damage. 1949 1 month, Beijing was peacefully liberated and well preserved, which is fortunate. Today, the Forbidden City in Beijing remains the same with a history of 580 years. Such a large-scale ancient building has been preserved for such a long time and in such a good condition that it is rare in the history of the world.

Today's Beihai Park is still the Royal Garden of Jindu! When the Yuan Dynasty established its capital in the Ming Dynasty, a large area of land in the north of the city was set aside outside the city, which was deserted. Although many city walls in Beijing have been demolished (for the needs of urban construction), some still have gates and towers, and some still retain ancient place names.
