The children had a lot of fun at Zhangye Danxia Landform Park. We experienced a hot air balloon for the first time. Although we were a little nervous, the time was a little short. We marveled at the magical power of nature, which has transformed such a beautiful and magnificent geological park. We hope that such a beautiful scenery can be protected for a long time. If we have the chance, we will definitely go there again to experience a real hot air balloon trip.
