"After the Wind-Volcanic Tunnel is Opened" is composed of 200 words.

I'm in front of the wind volcano tunnel. As you can see from behind me, this wind-volcano tunnel with a total length of 1.338 meters and the highest altitude has been successfully completed after one year! I saw that the builders at the scene were extremely excited, cheers resounded through the sky, gongs and drums roared, colorful flags fluttered, and the crowd rejoiced!

Seeing this, you may think, what's the big deal if it's just a through tunnel? In fact, this is the place where the Qinghai-Tibet Railway, the landmark project of the western development, will pass. The tunnel was dug a year ago.

However, how did this fierce "roadblock" yield so quickly? First of all, the frozen soil stands in front of the road-building army, but it is difficult to defeat our road-building army. Soon, the frozen soil was subdued. However, bad weather and extreme hypoxia hit the team in turn. However, through the experiments and research of scientific and technical personnel day and night, a large-scale oxygen station was built, and finally the eternal iceberg of the wind volcano was defeated! It can be seen that the success of the tunnel depends on the strength and wisdom of road builders and scientific and technological personnel!
