How to write a 300-word composition describing the scenery of Meijiang for primary school students

One day in the summer vacation, I came to Meijiang with my parents and members of the Che Youhui. It's so hot and the sun is so strong that the river is dry. We walked along the riverbed to Xianren Cave. The fairy cave is 254 meters high and 60 meters long. The cave structure is unique, like two steep arms. When it rains, you can watch the waterfall by boat and climb your arms. The cave is very cool and the wind is blowing gently. I really want to sleep in it. At this time, I took a child to play in the stream. I took a sip of the stream, sweet and delicious. This stream is very cold, which is in sharp contrast with the hot weather. My children and I are swimming in the water. I think this water can be called "the first water in the world" Meijiang Fairy Cave.
