Li Ke followed the uncle to the village, the whole village is not very neatly built, after all, this is on the mountain, always limited by the terrain, but every household is very clean.

The roads in the village are also clean on both sides, unlike many remote villages that are dirty, at least there is a lot of garbage and so on that are commonly used in the countryside.

And here, even some commonly used firewood is placed very neatly here, and there are garbage cans in the village, at least they don't see littering.

The acre of land reserved by each family is in front of and behind their own houses, and even the yard is very neat.

"Uncle, you guys are so clean here." The little assistant looked around with some curiosity and asked.

"Haha, of course, you may not believe it, our Zhangjia Village, or our various forest ranger villages in the entire Loess Plateau Nature Reserve are the earliest villages in the entire Datang to carry out garbage classification."

"For example, some of our daily household garbage, etc., these don't matter, they can be buried directly in the forest and finally fertilized to serve as nutrients in the forest. But if plastic or metal can't decompose naturally, or if it takes a long time to decompose, we just collect it and throw it down the mountain. The uncle said proudly.

Li Ke and the assistant were a little surprised, after all, a place like this, if it were any ordinary people, they might not be so clear at all, after all, there is a lot of land in the countryside, and it doesn't matter if you can litter casually.

For the people, they will not think so clearly.

Although Datang has been implementing garbage classification for a long time, since the uncle said that this is the earliest time that Datang began to implement, it means that the time for implementing garbage classification here is probably at least more than 100 years old.

"Then uncle, you are really amazing, after all, it is not easy to implement garbage classification in many cities." Li Ke said with a smile.

"Actually, it's nothing, our ancestors have been here for generations, and we can say that everything we have is dedicated to this mountain, this forest, and the trees in these forests are like our children."

"Now that we have caught up with the good time, we don't need to take care of the whole forest, we just need to patrol, supervise the forest situation in the whole mountain, or go to the fire house to station, avoid fires here, and monitor the animals in the nature reserve, and assist the relevant departments of the Forestry Bureau to study these animals."

"For example, our ancestors needed to plant trees in the entire Loess Plateau, and different trees needed to be planted in different seasons, and we also needed to take into account the types of vegetation, form a fixed ecosystem, avoid some biological invasions, and take care of animals."

"It was a difficult time, much more tiring than it is now, and there were not so many tools. Unlike now, the Wanghuo Tower is getting better and better, and some primeval forests can be patrolled by drones. ”

"Not only that, but there are countless meteorological satellites in the sky staring at these primeval forests, and if there is a possible fire point, they will notify us to inspect and so on."

"Technology has changed lives, and our work is much more leisurely now than before."

"The rest is all about this bit of household waste, can we still ignore it? Some daily household garbage, feces, feces and urine don't matter, just dispose of them in the forest. ”

"But things like plastic that may not decompose for thousands of years, and we certainly can't let it plague these forests."

"Because plants may not matter, but the animals that live in the forest eat the plastic, and that's a bad luck."

"We haven't forgotten our ancestors, our ancestors chose to stay, not just to protect nature, protect soil erosion, and prevent these loess that gave birth to our Chinese civilization from eventually becoming harmful loess."

"With us, protecting nature is not only about preventing soil erosion, but also about environmental pollution."

"So, we've been taught from a young age to do a good job of these protections, and that's naturally nothing. So you post-natal girls, it's okay to come here to play, but don't litter polluting garbage. ”

"It doesn't matter if you throw away food, melon and fruit residues, but don't litter plastics, cans, glass bottles, etc." The uncle looked at Li Ke and admonished.

"Don't worry, uncle, we won't litter." Li Ke smiled.

In this small village, what is reserved is not just an ancestral hall, Li Ke followed the uncle to see the ancestral hall in the village first, just like the uncle said, the entire ancestral hall is not piled up with stones like other places, but with rammed earth.

However, such rammed earth buildings have also experienced 1,400 years of wind and rain without falling down under the condition of continuous maintenance.

Li Ke put on a stick of incense, it doesn't matter. It was Li Ke of the Tang Dynasty Holy Sect who was incensed, what does it have to do with one of my anchors, Li Ke?

He's used to it.

In addition to the ancestral hall, there are many ancient buildings left in the village, such as the earliest Wanghuo Tower, which is also made of rammed earth, but after hundreds of years of wind erosion, coupled with no maintenance, it has weathered a lot, maybe it will not exist in another one or two hundred years.

In addition, there are traces of the terraces that were once used as terraces, but now these areas have long been covered by forests.

"Look at those ditches, those places were put in the past, according to the village records, once it rains, especially heavy rain, a large amount of soil will be washed down directly along the rain, and even if the rain lasts long enough, a large piece of soil will fall, forming a rolling torrent, or even a mudslide."

"But in our Loess Plateau, there have been no mudslides or flash floods for three to four hundred years."

"It is also for this reason that the Yellow River has become so clear now, and only a few limited places will become muddy."

The uncle took Li Ke and them to visit the entire Zhangjia Village, and then invited them to have dinner at home in the evening.

In the afternoon, Li Ke simply started the live broadcast, thanks to the progress of technology, such as the picture of the drone, etc., can be connected to the live broadcast room, today is the live broadcast of the Loess Plateau.

And for a large number of fans who live in the city and almost never visit these primitive jungle places, the stories in this are also unknown to them.

Just a simple story of Zhangjia Village made Li Ke harvest countless rewards in one afternoon, 1,400 years of perseverance, 64 generations of efforts, one by one Zhangjia Village made this Loess Plateau, which nurtured Chinese civilization, green again.
