Why is Zhengyangmen an old symbol of Beijing?

Zhengyangmen is located on the north-south axis of Beijing, south of Tiananmen Square and north of Qianmen Street. Now there are towers and arrow towers.

Zhengyangmen, commonly known as Qianmen, has a history of more than 500 years. Today, the predecessor of Beijing City is Yuan Shizu Kublai Khan's Dadu City in the northeast of Jinzhong City. The city is 60 miles long, the city gate 1 1, and Zhengyangmen (Zhengyangmen) is the right gate in the south.

Judy moved to Beijing after the Ming Dynasty destroyed the Yuan Dynasty. In the seventeenth year of Yongle (14 19), the south wall of the Yuan Dynasty moved 800 meters to the south, and the main entrance of Li moved to the present Zhengyangmen. At that time, it was also called the main entrance, and it was renamed Zhengyangmen in the first year of orthodoxy (1436).

In the fourth year of orthodoxy (1439), in order to strengthen the defense ability of the capital, the Arrow Tower was built outside the city gate of the capital, and the Zhengyangmen Arrow Tower was built at that time.

There is a huge urn between the watchtower and the watchtower, which is108m long from north to south and 88.6m wide from east to west. The urn has doors on all sides, all of which are arched doorways.

In the third year of the Republic of China (19 14), in order to improve the traffic conditions between the inner and outer cities, it was rebuilt into what we see today.
