[Explanation] Near the Wohu Mountain surrounded by green trees in Xizhang Village, Zibo City, Shandong Province, the Tibetan pig breeding base of the old man Chang Ailin is located here. The so-called breeding base is a naturally formed ravine.

In the breeding base, a group of black Tibetan pigs in free range are scattering for food and playing among the valley trees, as if they have come to the "Wild Boar Forest" in the Water Margin.

  [Explanation] On November 13, the reporter saw at the Tibetan pig breeding base in Chang Ailin that he was nearly 60 years old feeding Tibetan pigs, and a cart full of fresh pumpkins and cabbage was delivered to Tibetan pigs.

Chang Ailin said that the reason for breeding is because of his childhood love for animals.

  I loved animals when I was a child. I started raising bees when I was fifteen or sixteen. I fed pigs and sheep. At that time, my family was poor and I carried a basket to hogweed.

I have been to Tibet a long time ago. I saw Tibetans raising Tibetan pigs in the mountains and on the grasslands. I bought 5 piglets at that time, and I have raised more than 2,000 piglets before 2010.

  [Explanation] When Chang Ailin talked about the "wild boar forest" in this ravine, he told reporters a special experience.

Chang Ailin was born and grew up in a mountain village, and has a special affection for mountains and forests.

In 1998, despite the opposition of his family, he used all his savings to circulate more than 300 acres of barren hills and wasteland in the village, determined to turn the barren hills into lush green hills.

Since then, Chang Ailin will plant trees as part of his life. Just like his name "Chang Ailin", he loves the plants and trees he planted by himself.

After unremitting efforts, Chang Ailin turned barren hills into green hills.

This green hill also provides a natural living space for Chang Ailin's future Tibetan pig breeding.

  My place has natural conditions, it is high all around, there are vegetation, these trees I planted.

When we contracted this place, there was no road, no water, no electricity, nothing, a bare piece of land, not even a small tree. Our soil is loess and it is easy to slide.

This does not plant more than 10,000 trees.

After planting the tree, it is bad and basically there is no landslide.

  [Explanation] The reporter saw at the breeding base that there are small caves on the hillside, which look like cave dwellings where people live. Many Tibetan pigs are lying and resting in the caves. People who come here call these caves. It is called "Pig Cave Dwelling".

Chang Ailin said that Tibetan pigs are free-range pigs, and the caves are specially built according to their living habits. This kind of breeding method is much better than ordinary captive methods.

  After the pig was covered with a pen, the environment changed when it was covered with concrete, and the natural breeding method was changed, and the cost of burrowing in soil was also reduced.

When I first started selling, some people who came to play saw the free-range Tibetan pigs. The meat of her was really delicious once it was eaten. After that, it will be popular for ten or ten years, and now the market is not worried.

  [Explanation] In addition to selling Tibetan pigs raised by Chang Ailin to pork processing plants, it also attracts residents from nearby cities and pet shop owners to buy Tibetan pigs as pets. The economic benefits are considerable. Now, Chang Ailin's annual income can reach 500,000 yuan.

In the future, Chang Ailin intends to continue to expand the scale of the Tibetan pig breeding base, so that specialty breeding will become a new way for more villagers to increase their income and become rich.
