People may have to go through many places in their lifetime, but they can make you remember a few fresh words, such as noisy city, busy street, gray sky. These words are like the mantra we often say in our mouth, fading prosperity, we can immerse ourselves in the endless grassland, watching the blue sky we have not met for a long time, breathing the only trace of fresh air, even if it is. The sky is cloudy and you won't feel a little depressed. A few lines are not enough to express my admiration for Hulunbeir Grassland. The following pictures are taken by me. Please give me some advice on the shortcomings.
