Every train will whistle for 30 seconds. Do you know why?

In Heijing Township, Lufeng County, Yunnan Province, China, there is a bridge at the steepest place in chengdu-kunming railway, called Longgudian Bridge. Every train passes by, it will honk for 30 seconds. This is in memory of China soldier bear. During the construction of Longgudian Bridge, a shocking story happened.

Longgudian Bridge was the most difficult part of the construction at that time. At that time, due to the weather, there were problems in the construction process, so the monitor Xiong went to check it out. He was exhausted by the long work, but he didn't stop and fell straight down. Below is the pier being watered. The building cement solidified quickly, so his comrades could only watch and didn't have time to rescue it. At this time, Dr. Xiong was only 2 1 year old, unmarried and childless. But he was too young to say at the last moment of his life: let me know when the bridge is repaired! ?

At that time, the bridge repair technology was not very advanced, and the progress of pier construction was very slow. If you want to take out the remains, you have to blow up the bridge, but this does not guarantee the integrity of the bear's remains. For the sake of construction progress, it was finally decided to combine the remains of Xiong Martyrs with the piers. At that time, there was a special military class in China called Infrastructure Engineers, which means that all the soldiers who built the bridge at that time came from China. Mr. Lu Xun once said: Since ancient times, we have people who work hard, people who work hard, people who defend the people, and people who give their lives for the law ... This is the backbone of China. These people are the backbone of China.

Later, every time the train passed by, it would whistle, which is why it would whistle for 30 seconds every time the train passed by. The purpose is to tell the bear that the Martyrs Bridge has been repaired and you can leave with confidence! 13 The word:? Bear is a martyr through the ages, an old soldier of Kuntie? . In fact, there is a saying that is particularly good? No time is quiet, but someone is willing to carry the burden for you. ? Here, I would like to pay tribute to Dr. Xiong.
