Deshengmen has been an important transportation hub in Beijing since ancient times. Deshengmen is the starting point of Beijing-Tibet Expressway (G6 formerly Badaling Expressway), connecting the northern part of Beijing. Because there is a subway car factory nearby, Jishuitan subway station has become the earliest subway transfer station in Beijing.

Origin of the name of Deshengmen: the stars in the north belong to Xuanwu. Xuanwu is the main swordsman, so he sends his troops to fight and usually goes out of the city from the north gate. The reason why it was named Deshengmen means "winning by virtue" and "winning by virtue". In case of war, sending troops from Deshengmen and moving troops from Andingmen respectively means "capture the flag" and "peace and stability".

It is an important gateway for the capital to Saibei, and is known as the "military gate". Emperor Yongle's Northern Expedition in the Ming Dynasty, Emperor Kangxi's suppression of the rebellion in galdan in the Qing Dynasty, and Emperor Qianlong's suppression of the rebellion in Dazhuo were all successful. During the Ming and Qing Dynasties, Deshengmen resisted the military invasion from the north and was the most important city defense position in Beijing. The famous Beijing Defence War happened here.
