Not far north along the central axis from Yongdingmen, you will see the Temple of Heaven on the left and Xiannong Altan on the right (now part of the Ancient Architecture Museum and part of the Beijing Yucai School). Further ahead is the overpass where folk artists such as storytellers, opera singers, showcases, dragoers and other folk artists gather. Now, on the Bell Tower Square, there are several lifelike statues of rap and vaudeville artists. The flagship store of Deyun Society is also located nearby. During the Ming and Qing Dynasties, there was indeed a white marble stone bridge here, which spanned the river in a north-south direction. The emperor would pass this bridge every time he went to the Temple of Heaven to worship heaven, so it was called Tianqiao, and hence the name of this area. Later, due to the decline of the dynasty and the development of the city, the river under the bridge became narrower and narrower, gradually evolved into Longxugou, and finally became an underground river. The bridge was completely demolished. In 2013, in order to restore the landscape of the central axis, the Beijing City government rebuilt the overpass. However, due to the tremendous changes in the road layout, in order not to affect traffic, the newly built overpass was moved south about 40 meters from the original site. It is said that a mark was made on the original site, but I have been there several times and failed to find it. There is a channel under the bridge. The walls on both sides of the channel introduce the main bridges on the central axis and the components on the bridge in the form of pictures. It is worth a visit.

From the overpass to the front door, both sides of the road are relatively dilapidated and have been in the state of renovation. The exposed land on the roadside is covered with green dust nets, and fences are erected on the street. Behind the fence is the old Hutong civilian area. It is said that it has been renovated for more than ten years. Progress is slow. So this section can be skipped directly by bicycle.

Qianmen Street is now a bustling commercial street, and almost all tourists from all over the world come to Beijing. "The front gate building is 99 feet tall, the four gates, three bridges and five archways","the front gate building is 99 feet tall, and the nine alleys are nine willows","the front gate building is 99 feet tall, and the Dazhalan faces the fresh fish mouth", you can still imagine what the street looked like at that time through the jingles passed down from ancient times. In addition to modern Chinese and foreign brands, Qianmen also retains some traditional time-honored brands, such as Quanjude Roast Duck Restaurant, Duyichu Shaomai Restaurant, Qianxiangyi Silk and Dover Restaurant, Tiantongmutton Restaurant, Zhang Yiyuan Tea House, Dabei Photo Studio, etc. As the brand inherits for a long time, there will be more stories, so behind every time-honored brand there is a legend closely connected with the destiny of the country and the times. Xianyukou is a food street. There is a cheap fang roast duck restaurant with a history longer than Quanjude, so I don't want to try it. It is said that there is a restaurant that serves the best fried liver in Beijing. There is no "one". I will definitely go and look for it when I have time. There is a bookstore called Page One in Qianmen that is also unique. On its second and third floors, there are two large south-facing floor-to-ceiling windows, directly facing Zhengyang Gate. This is worth a visit.

The Zhengyangmen Arrow Tower and Zhengyangmen Tower on the south side of Qianmen Street stand on both sides of the bustling road. People who shuttle through them every day are accustomed to him. With the popularization of mobile phones, they have no time to care about him. But if you knew that he had been standing there for two or three hundred years and that he had witnessed the historical changes of Beijing over the past few hundred years, would you still despise him? At least I won't.

Across the wide Tiananmen Square is the Forbidden City. It basically takes a day to visit the Forbidden City, so I chose to take Nanchizi Street on the east side of the Forbidden City for this section of the Forbidden City. Nanchizi Street and Nanchang Street are two symmetrical streets on both sides of the Forbidden City. They are completely different from the hustle and bustle of Chang 'an Street. There are fewer vehicles and tall national locust trees on the roadside, which is particularly quiet. This time, I accidentally discovered "Huang Shi". I heard about the emperor's history from Professor Yan Chongnian's series of lectures on "Six Hundred Years of the Forbidden City". It is mainly a place where the emperor's family tree is preserved. The emperor's family tree is also called the "jade archive" and is compiled and renewed every ten years. The jade archive is about 90 centimeters by 50 centimeters in size. Professor Yan said that once he went to visit the jade archive, which was carried by two people at that time. I have never seen such a big book before. I heard that the emperor's history has been opened to the public and can be arranged on the future schedule.

Jingshan Park north of the Forbidden City is a place I particularly recommend. The park is not big, and a two-yuan ticket is basically free for the royal garden. One of the most distinctive attractions in the park is the Wanchun Pavilion on the top of Jingshan Mountain, not only because it is the best location to look in all directions and overlook Beijing (I was shocked when I first looked at the Forbidden City from this location), but also It is also the place where the east-west and north-south central points of the inner city of Beijing meet. Not far from Wanchun Pavilion is the place where Emperor Chongzhen died. Emperor Chongzhen was martyred in 1644. 300 years later, in 1944, Japan invaded China on a large scale, and China was once again on the verge of subjugation as in 1644. Patriots at that time erected monuments here. One was the "Place where Emperor Sizong of the Ming Dynasty was sacrificed to the country" and the other was the "Monument to the Three Hundred Years of Emperor Sizong of the Ming Dynasty was sacrificed to the country", which was quite patriotic. In recent years, Beijing's central axis has been applying for cultural heritage, so many scenic spots that were not previously open have been restored. Huang Shizhen is one of them, and the Shouhuang Hall on the north side of Jingshan is also one of them. After ten years of restoration, the Shouhuang Hall is now resplendent. Seeing is better than hearing everything, and it can also be arranged on your future schedule.

Outside Jingshan, if you go north, you can taste old Beijing snacks at the Huguo Temple Store at the intersection of Di 'anmen Gate. My favorite is fried cake, which tastes comparable to Tianjin Eryan fried cake. In addition, you can also taste bean juice. Of course, it can also be regarded as a challenge.

200 meters further north is the Wanning Bridge. It is located on Di 'anmen Nei Street and still carries modern transportation functions, with countless pedestrians and vehicles coming and going every day. Although it does not seem to be very famous, you must not underestimate him. Some of the lions on the capital and the water-holding beast under the bridge are original to the Ming Dynasty. There are even two small beasts from the Yuan Dynasty lying underwater, all over a few hundred years old.

The northernmost end of the central axis is the Drum Tower and Bell Tower. The Drum Tower and Bell Tower are ancient time-telling places. There are usually exhibitions on ancient timing methods and timing tools, and sometimes there are performances of beating drums. The square between the Bell and Drum Towers is a place for nearby residents to relax. It is sheltered from the wind and sunny to the sun, and the sun in winter is particularly warm. I once read a novel written by Liu Xinwu called "Bell and Drum Tower". It tells the story of the Bell and Drum Tower in Beijing in the early 1980s. The whole book describes the life of all sectors of society through stories that occurred in 12 hours. Scenes, showing Beijing life and social changes in the 1980s.

From Yongding Gate to Bell and Drum Tower, the central axis is 7.8 kilometers long. Maybe you can't see this line, but when you think in your heart that it is a famous and only line in the world, this line runs through the glorious masterpiece of ancient Chinese architecture, embodies the philosophical concept of Chinese culture, and carries the historical accumulation of Chinese civilization. When you think about this in your heart, you will feel different when you walk.

Today, the central axis of "New Beijing" has extended northward from Gulou Wai Street, leading directly to the world-famous Olympic Forest Park. The Bird's Nest and the Water Cube are on the east and west sides, which implicitly conforms to the concept of a round sky and a square earth, and finally ends at the Olympic Forest Park. The main peak of the park faces the mountains. The newly opened central axis is called Beichen Road, which should come from the Analects of Confucius,"govern by virtue, for example, Beichen, where it lives and is surrounded by stars."
