After the big man said these words, everyone did not speak for a long time. I don't know if I was frightened, or if I was hit by the natural conditions in front of me.

I couldn't help but look at everyone around me: the old man still had a kind face, and he didn't see any panicked look; Seeing his appearance, he didn't seem to have any pressure or discomfort in the cold and harsh environmental conditions. It also reminds me that our previous worries were completely unnecessary.

Looking at the old ghost again, his face was full of sadness, as if he was full of worries about this trip. Although he didn't say anything as he usually did, a lingering sadness could be seen between his frowning brows.

On the other hand, Duoduo and Lisa leaned against each other, as if they were encouraging each other because of the cold. This makes me feel that the two of them are really a pair of good sisters who transcend life and death.

Qian Ying, who was not far away, was accustomed to this qiē, and he didn't see any worries or concerns, which made me feel a little strange. Supposedly, he won't be in such a situation very often. Could it be that as he himself said, life and death are no longer so important?

The big man was as calm as ever, and he didn't seem to be surprised. At this moment, he was using his sharp gaze to sharply examine the qiē in front of him. He saw that everyone was silent at the moment, so he simply finished speaking.

"Avalanches, like floods, have recurring," he said. That is, if an avalanche occurs somewhere, it is entirely possible that it will come back soon after. It is possible to have an avalanche in the same place every snowfall, every year or every century, depending on the topography of the slopes and certain climatic factors. ”

Seeing that everyone was said to be in a downturn by the big guy, I was a little worried. So I said to the big one, "Big brother, you said so much, and it is detailed enough. If there is an accident, there should be measures to deal with it, right? ”

Listen to me, big man. hurriedly said, "You asked this question well!" Since there is a disaster, there must be protective measures. However, although it is protection, it is actually to do your best to minimize the loss. In general, there are several proven methods: the first is blasting. ”

"Blasting?" The old ghost and I asked in surprise at the same time.

"Hmm. In many places, artillery shells are fired at some dangerous areas to explode, causing avalanches with less snow in advance, and special personnel are set up to monitor and forecast avalanches. In this way, it can not only effectively prevent the occurrence of large avalanches, but also reduce casualties.

Many countries, such as the countries surrounding the Alps, Norway, Iceland, Japan, the United States and Canada, have set up special organizations in areas prone to avalanches, and have special monitoring personnel to detect the natural patterns and preventive measures of its formation. The big man said.

Because it's a matter of life, we listen very carefully. Listen to the big guy talk about the method. Coupled with our imagination, we found that what he said really had a certain truth.

Seeing that we nodded again and again, the big one continued: "The second way is to borrow the time of the sky. ”

"Borrowing time?" The old ghost and I asked again in surprise.

"Well, 'borrowing the day' means to observe the principle of activity in the avalanche high-risk area: pedestrians and vehicles should not enter the avalanche high-risk area during heavy fog, snowfall, snowfall, warm wind, or the next two days.

Walking on a ridge is safer than in a valley; The snow on the north-facing slopes tends to collapse in winter, and the snow on the south-facing slopes tends to collapse in the warm spring. These are the laws of nature. It is necessary to closely observe the signs of avalanche and be vigilant in case of accidents. Adapt to the weather! ”

This time, the big man didn't wait for us to ask. Just said: "Once you encounter an avalanche, you must quickly rush to the side to escape the collapsing snow flow; or grasp trees, rocks and other relatively solid objects; Or use an ice axe to pierce into the deep snow to immobilize your body, trying not to get yourself and your partner washed away.

If you accidentally get caught up in the snow, immediately close your mouth, head towards the top of the mountain, and move your limbs vigorously. Aim to be on the surface of the snow stream. When the snow stops, cross your arms over your chest. Try to expose the area required for mouth, nose, and thoracic movement (breathing).

In case of misfortune, the snow is huge and buried. Struggling is almost useless, and the only thing to do is to conserve as much energy as possible and shout loudly when there is a chance to do so. ”

"Huh? Just wait for death? "The old ghost couldn't believe what he was hearing. At the same time, he asked, "Isn't there any other way to do it?" ”

The big man said, "I'm talking about the most effective method!" You might as well think about each of the methods I've talked about and see what the results would have been if you hadn't done it that way. ”

The old ghost said, "Then I'll have to give it a try, what's the first method you just said?" ”

"Blast!" The big man said, "What do you think would happen if you hadn't done early blasting?" ”

"Oh yes, blast!" "If you don't blast it, the snow will be very heavy." Then, someday there will be a concentrated eruption! Moreover, the perennial snow erupts and is definitely overwhelming and unstoppable. No, no, it seems that it is better to follow the method you said. And what about the second one? ”

"The second is 'borrowing the time'." The big man said.

The old ghost thought for a moment and said, "This second kind has nothing to say, 'Shuntianshi' is an undoubted method since ancient times. Even if I don't believe it, I have to believe it, since it has been inherited for thousands of years, it must have its truth. ”

"The third is fixation and closure." The big man said directly.

"Well, it seems you're right. I believed! ”

The old ghost originally wanted to overturn the big man's theory, but after looking around, he still couldn't find a loophole in the big man's method, and finally had to be convinced.

"In that case, do you remember that?" The big man asked.

We all nodded at once, indicating that we knew what he was telling him by heart. The big man stopped explaining and continued to check the way in front of him. There was only one of us who seemed to disagree with the way the big man said it—and that was the old man.

At this time, I just don't know what the old man thinks? He always listened to us with a smile, but he didn't say a word, and seemed to know everything about it.

Although the big one is simple and clear, we have a deep memory. Whether we encounter a big avalanche or not, it is good to learn something.

Just when everyone was still recalling the method that the big man said, there was a "boom" sound in front of us!

It's not very loud, but it's moving! (To be continued......)
