　　On August 23, General Secretary Xi Jinping visited the Saihanba Mechanical Forest Farm in Hebei Province for investigation and investigation.

　　Saihanba is located in Weichang Manchu and Mongolian Autonomous County of Chengde City, Hebei Province. Historically, it is rich in forests, beautiful water plants, and numerous birds and animals.

　　However, due to reclamation, years of wars, and continuous wildfires, before the founding of New China, Saihanba gradually degenerated into a plateau desert with "yellow sand covering the sky, flying birds without trees".

The picture above shows the wasteland before the construction of Saihanba; the picture below shows the current Saihanba.

　　In the autumn of 1962, 369 first-generation builders faced the billowing cold and sounded the battle clarion call "for trees from barren mountains" in the snowy Saihanba.

　　After three generations of Saihanba builders' "green relay", the forest farm has a forest area of ​​1.12 million mu, becoming the world's largest planted forest.

The forest coverage rate increased from 11.4% before the site was built to 80%.

　　The forest sea of ​​Saihanba effectively blocked the southern invasion of the Hunshandake sandy land and improved the microclimate of Saihanba and surrounding areas. It can absorb 810,000 tons of carbon dioxide and produce 550,000 tons of oxygen each year.

　　Today, Saihanba is picturesque in four seasons, and it has become "the source of the river, the hometown of clouds, the world of forests, the sea of ​​flowers, and the paradise of rare birds and animals."

　　"North China Emerald" deserves its name!
