Change of development

In my stamp book, there are several stamps that are very precious to me - Zhaozhou Bridge, Nanjing Yangtze River Bridge, and Nanpu Bridge.

Although Zhaozhou Bridge is "the age is high," the style is still the same. It is 50 meters in length and 9 meters wide. It runs in the middle and walks on both sides. The bridge is made of stone. There are no piers underneath. There is only one arched bridge hole that spans over 37 meters wide. It is the earliest stone bridge in the world. Li Chun, a stone mason of the Sui Dynasty, has a unique ingenuity and fully embodies the wisdom of the ancient working people. The bridge is not only sturdy, but also beautiful. It is really praised.

However, in the poor and backward old society, more wooden bridges were created. The single-wood bridge is very simple. It is just a trunk that is placed on both sides of the river. It has a simple appearance and many shortcomings. The mood when crossing the river can be said to be: water, heartbeat, and fear of crossing the wooden bridge.

After the founding of New China, the Dumu Bridge became a cement bridge. The original bridge was just a walk away. Now, even the motor vehicles are on the cement bridge. Under the care of the party and the government, the Chinese people built up Nanjing with wisdom. The Yangtze River Bridge, the undulating river, nine huge piers firmly support the bridge, the bridge is divided into two floors, the next layer is the train, paved with two tracks; the upper level is the road, the road is the sidewalk, the car How convenient is the car. In response to that sentence: "One bridge flying north and south, Tianzhu changed the way."

Nowadays, criss-crossing bridges are more common. For example, an overpass bridge has a small bridge. It can make many vehicles pass at the same time. The scene of the car crossing the bridge is like a vivid picture. The Nanpu Bridge was also built on the Huangpu River. It is the first cable-stayed bridge in China. Next to the main bridge is a black and thick cable-stayed cable. The middle section of the bridge has Deng Xiaoping, the chief designer of China's reform and opening up. The four vigorous characters of the grandfather's self-written title "Nanpu Bridge", under the bridge is the tamed Huangpu River, and the passenger ships and ships that traveled freely. The completion of the Nanpu Bridge not only facilitates transportation, but also becomes a striking landscape in Shanghai.

Look at the stamps in your hand and think about the changes in the bridge. I think China has undergone earth-shaking changes, and the future of the motherland is so beautiful. I believe that in the future, our young Chinese teenagers will create more miracles and build more advanced bridges. It’s really "small changes, big development"!
