Mulberry fields are planted on the slopes of the hills, although they are not high, but for the paddy fields, the difference between high and low is very obvious.

Zhixin shook his head and said: "The ancients said: It is better to read 10,000 books than to travel 10,000 miles, which means that you should study hard, let your talents be excellent, let what you have learned be reflected in life, and at the same time increase your knowledge, that is, combine theory with practice and apply what you have learned." ”

Hao Hao praised him: "That's right!"

Ai Wanying said with understanding: "Don't talk about the children, I also follow the long knowledge, it seems that when I have time in the future, I have to take the children around." ”

Youyou thought to herself: "Mom, it's not just time to go out for a walk, but also to have great unity." Now that the problem of food and clothing has just been solved, there are not many people who have the conditions to walk around. ”

At six o'clock in the evening, a tall and majestic bridge came into view, and Grandpa Zhibin, who was sitting in front, excitedly shouted: "Nanjing Yangtze River Bridge!"

There are not many vehicles on the bridge, the car is in the middle of the bridge, stopped on the side of the road, Hao Hao opened the car door, jumped down first, Zhiliang was in the car, the two cooperated, and helped the four old people down first.

After the children got out of the car, they quickly stepped over the guardrail and walked onto the sidewalk. There are a lot of tourists on the sidewalks on both sides of the bridge, but most of them are concentrated on the sidewalks on the east side, which is more suitable for taking pictures. On the sidewalk, there were more than a dozen people with photo signs around their necks.

At six o'clock in the afternoon, the light is perfect for taking pictures, and people lean on the railing of the bridge, facing the sunset, smiling comfortably, with the sound of the shutter, leaving unforgettable memories.

Seeing so many people getting off the car, people who took pictures nearby surrounded them and solicited customers: "No, take pictures, three yuan a piece, it's advisable to wait immediately." ”

When they saw the camera around their necks behind them, several people immediately withdrew.

My family not only brought a camera, but also a video recorder, and the people around them also automatically retreated, but they didn't leave too far, stopped a few meters away, and watched curiously. Many of them have never seen a video recorder before, and they have a natural resistance to unfamiliar things.

This time, there was an entourage, and the whole family took a lot of group photos, and they took all the film in several cameras before they stopped.

The surrounding crowd was stunned and discussed: "This group of people is really rich, how much does it cost to take so many photos!"

Grandpa Zhibin was more excited than everyone else, he said: "I used to teach students the text "Nanjing Yangtze River Bridge", just looking at the pictures to teach, but now I feel even more shocked when I am there. ”

In order to teach, he spent a lot of time on the bridge, collected a lot of information related to the bridge, and taught on the spot today, giving the children a vivid Chinese lesson.

Nanjing Yangtze River Bridge is the first railway and highway dual-purpose bridge designed and built by China on the Yangtze River, which is of great significance in the history of bridges in China and even in the history of bridges in the world, and is an important achievement of China's economic construction in the 60s of the 20th century, an important milestone in China's bridge construction, and is known as the "bridge for energy".

Nanjing Yangtze River Bridge is a double-decker bridge, the upper layer is a highway bridge, 4589 meters long, the roadway is 15 meters wide, can accommodate 4 large cars in parallel, there are more than 2 meters wide sidewalks on both sides, connecting 104 National Highway, 312 National Highway and other cross-river highways, is one of the main roads connecting Nanjing Jiangbei New Area and the main city in the south of the Yangtze River.

The lower layer is a double-track double-track railway bridge with a width of 14 meters and a total length of 6,772 meters, connecting the Jinpu Railway and the Shanghai-Nanjing Railway trunk line, which is the main and lifeline of the country's north-south transportation.

The bridge is composed of two parts: the main bridge and the approach bridge, the main bridge has 9 piers and 10 spans, a length of 1,576 meters, and a maximum span of 160 meters. The navigable clearance width is 120 meters, and the navigable clearance height under the bridge is 24 meters above the design maximum navigable water level, which can pass through 5,000-ton sea vessels.

There are 150 pairs of magnolia-shaped street lamps on the sidewalks on both sides of the main highway bridge, which are exactly the same as the street lamps on Chang'an Avenue in Beijing.

The duplex bridgehead of the Nanjing Yangtze River Bridge has distinctive characteristics of the times. At the north and south ends of the main bridge, there is a pair of bridgeheads and a pair of small bridgeheads.

The tower is 70 meters high, 11 meters wide, beige, stands on both sides of the bridge, the big fort protrudes high above the highway bridge deck, and the top is 5 meters high, 8 meters long steel "three red flags", showing a leap forward. After the completion of the bridgehead, the characteristic style of "three red flags" swept the country and was imitated many times.

The fort has elevators to the park under the bridge, the railway bridge (closed to the public), the road bridge and the platform at the top of the fort.

The small fort is located at 68.7 meters from the big fort to the approach bridge, and the structure, appearance and color are similar to the big fort, but the volume is slightly smaller. The part of the small fort protruding from the highway bridge deck is a 5-meter-high gray concrete group portrait of "workers, peasants, soldiers, scholars, and businessmen".

In the lower part of the bridgehead deck, the side of the big fort is written with large red slogans such as "Long live the great unity of the people of the whole world" and "Long live the great unity of the people of all ethnic groups in the country", and on the side of the small fort are written "The people, only the people, are the driving force to create world history".

The creation of the relief is influenced by the relief of the Monument to the People's Heroes and the top ten architectural sculptures in Beijing, which integrates the realistic techniques of European sculpture, the composition of Chinese landscape painting and the tradition of portrait stones in the Han Dynasty, and organically combines utopian imagination, ideology and artistic expression. The relief of the bridge railing is in harmony with the style of other decorations of the bridge, reflecting the distinctive style of the times, and is a classic work of popular art at that time.

Finally, the old man affectionately recited the original text of "Nanjing Yangtze River Bridge":

Early in the morning, I came to the Nanjing Yangtze River Bridge. Today's weather is exceptionally good, with white clouds floating in the blue sky. The bridge looks magnificent in the bright sunshine. In the rolling river water, nine huge piers hold the bridge body steadily. The main bridge is connected to the 22-hole approach bridge, as if a steel dragon is lying on the river. The bridge is divided into two levels, the lower one is the railway track, paved with double tracks, and the upper one is the road, and the two sides of the road are sidewalks. On the wide road, pedestrians and vehicles come and go as if they were shuttling.

I walked along the sidewalk and approached the main bridge. Two majestic statues of workers, peasants and soldiers stand on the left and right. Behind the statue, there are two tall bridgeheads, and the red flags at the top reflect the sun, which is very gorgeous. On the straight road of the main bridge, a pair of magnolia lampposts, like a queue waiting for review, stand neatly and neatly. I held on to the railing of the bridge, stood on the bridge, looked at the river, the steamers on the river were like a leaf boat, with the waves rising and falling, listening attentively, the trains whistled, whistling from under the feet.

The surging river is mighty and rushes to the sea. The Yangtze River, known as the moat since ancient times, has been conquered by us. A bridge flies north and south, and the moat becomes a thoroughfare.

After the old man finished reciting, there was a round of applause around him, and many people sighed sincerely, one of them said a middle-aged man pushing a bicycle: "I often pass by on the bridge, and my understanding of this bridge is not as profound as your old age." ”
