The lush greenery of the Huangshan Mountain, the clear green of the Xiaoxiang water, breeds the growth of everything in the Zero Mile Basin. Under the natural conditions of unique geographical area, comfortable climate, good environment and high-quality soil, the Huangshan Mountain pigs play freely and freely. Hungry, eat a grass; thirsty, drink a mountain spring; tired, sleep to wake up naturally. It is this kind of mountainous pastoral life like Peach Blossom, which has created its unique and excellent quality - pure, natural, high nutritional value, no drug residue.

[Landmark Geography] The beautiful and beautiful Xionghuang Mountain forms a natural zero-lying basin with the Siming Mountain in the northeast and the Yangming Mountain in the south. It administers Lingling, Lengshuitan District 2 and Xiangyang, Dong'an and Shuangpai counties. 5,704 square kilometers, after the intersection of Lishui and Xiangjiang River, Pinggang interweaves, Tianlian is a stranger, and the network of water is obvious. It is one of the commodity grain bases in Hunan Province. The soil in the Zero-Yuan Basin is fertile and is a typical subtropical humid monsoon climate zone with four distinct seasons and abundant rainfall. The annual average temperature is 17.6 °C to 18.5 °C, and the frost-free period is 286-311 days. The wild forage resources are particularly rich, and the grasses in the field are abundant. There are dozens of high-quality pastures such as wild peanuts, thousand-story buildings, four-wheeled grasses, and water bamboo leaves. Scattered between the basins, the simple mountain households are fed a native pig, which is the Yongshan mountain pig with the characteristics of Yongzhou.舜皇山土猪, the scientific name "Dongan pig". In 1971, it was rated as one of the local fine varieties by the National Livestock and Poultry Breeding Association. Its appearance is: nodding ink tail, butterfly ear, short mouth, bobbin body, cattle eye. That is, the hair color of the head and tail is black, the other parts are all white; the head is short and wide, and the face is slightly concave; the ear is medium-sized and shaped like a butterfly; the forehead has wrinkles, the back is flat, and the abdomen is large but not dragged. [Cultural background] A long time ago, there was a dutiful son named Chen Shun in Lingling. His mother was sick for many years. He often stayed up all night, and he did not understand the clothes and served his mother. The soup that the mother served, he will try to let his mother take it after he tasted it; even endured the pain, and took the family to cut off his own meat to make medicine for the mother. When the Emperor Sui visited the south, I heard that Chen Shun’s deeds were very moving. On the mountain road to visit him, he hunt a group of pigs. His nod ink tail, like snow, ears like butterflies, headband "Fu", even Rare, brought to the Chen family, immediately slaughtered one to give the mother to cure the disease, the meat of the food is delicate and delicious. After Chen’s mother’s appetite, her appetite increased greatly, her spirits renewed, her body’s illness was greatly alleviated, and she was soon cured. When Emperor Sui was overjoyed, he gave the pig to Chen Shun. Chen Shun carefully raised and multiplied and divided the mountain people. Later, in the Lingling area, there was a unique pig in the world. In order to commemorate the Emperor Sui, the mountain where the Emperor Sui lived was called the Emperor Huangshan, and the pig was named the Suihuangshan soil pig. The story adds a strong cultural atmosphere to the Huangshan Mountain pig. In fact, the Huangshan Mountain pig is an ancient local species that originated from the wild boar captured by the ancestors and has been domesticated, cultivated and selected for a long time. According to "Yongzhou Fuzhi", "Lingling District Records" and "Dongan County Records", the breeding history of the Suihuangshan soil pigs is more than 5,000 years old. In the Shang and Zhou dynasties, local pig production has been very developed. This shows that the Yanhuangshan soil pig has a long history of formation, and it is also a product of local people's hard work and long-term breeding and integration with local natural and economic conditions. [Cultural Accumulation] In the late 1980s, Dongan writer Yi Xiangen wrote a special recollected essay "The Emperor of the Emperor's Mountain", which was written by the Emperor Huangshan. Pig, a special type of pig with short mouth, short legs and short tail, is a native pig. This kind of pig looks like a big winter melon, the temperament is exceptionally gentle, the color is black and white mottled, because the feed is mainly based on cereal grains and grass and leaves, so it is also called rice pig or grass pig. It is very similar to the white-browed owl in the Huangshan Mountain. White-browed blemishes are a kind of wild game with a delicate and tender taste. It grows in the mountains, and it is usually hidden. Only after the white dew, when the jujube is ripe, it can be caught. It turns out that this kind of white eyebrows loves to eat jujube. It quickly climbed the branches with claws and stretched its neck to swallow sweet and sour dates. This guy is very greedy, swallowing his mouth, until the belly is swollen like a pregnant woman, still not letting go. The more you eat, the more greedy you eat. The more you greedy, the more you climb up. The more you climb, the bigger you eat. The more you eat, the bigger the stomach, until the ball is like a round ball. Naturally, you can’t come down. You have to fall from the top of the tree and slammed into the past. Lying on the ground does not move. If someone catches up at this time, you can catch it and take it home as a good meal. If the first half of the hour, no one to catch it, it will come back to God, spread four short legs, escape, hide in the cave, beautifully digest the full stomach food. After the enjoyment is completed, it repeats itself, so that it grows fat and fat, and becomes a delicious food chased by the mountains. Thinking of the shape and taste of the white-browed man, I thought that the earth pig of the Huangshan Mountain could be the same as the mountain treasure of the Huangshan Mountain. This kind of primitive conservation practice of the Huangshan Mountain pig, the original ecological growth environment, and the simple farming method have aroused the attention of many media such as CCTV. At 18:30 on May 30, 2013, CCTV's seven sets of "Science and Technology Court" broadcasted a record of the "Hub Freedom and Happiness". The film lasted for 30 minutes, and the suspense of “Deep Mountain Treasures” led to the Huangshan Mountain pigs, followed by the Yitang, Dajiangkou breeding base, Hunan Henghui Food Co., Ltd. deep processing base and some farmer farms. The whole process of free and happy growth of the pigs in the original ecological environment was photographed in an angled way. The changes in piglet insulation measures, changes from small to large sports venues, fruit gardening, pig feed formula and feeding methods were recorded. The pigs and the sows are naturally mated and transported to the slaughtering process to provide safe and delicious pork. The film takes the story as the leader, and the shooting quality is beautiful, which makes people seem relaxed and happy. After the broadcast, it caused a strong reaction. It is a good film that comprehensively records the Huangshan soil pig.
