Introduction to the Three Thousand Years Forest Area: Three thousand years of Populus euphratica are in their prime. They have gone through the test of drought and salt immersion. Their bodies are strong and strong, and their muscles and bones are clear and tough. They are like warriors wearing armor with hot blood and eyes. There are blazing flames inside, and soaring pride exudes in the chest. Unstoppable is their promise, indestructible is their oath, and the clanging flag is their horn and cry.
