Tell me a few sentences describing the action and demeanor of people flying kites.

There are a lot of kite flyers in the square, some standing, some sitting, and some running. They are all looking up with their mouths open, holding a spool of string in one hand, pulling a long line in the other, and staring at their kites with their eyes fixed on them.

High in the sky, an eagle and a swallow are flying high. The swallow was flying higher and higher, and was about to overtake the eagle. At that moment, the owner of the eagle was also not afraid to let go of the spool of thread in his hand. Next to them, several cranes were dancing beautifully, and the centipede on its head was twisting its long tail and fluttering in the air with the wind. There are a lot of people here, all looking up, pointing, gesticulating and talking.

My mom, dad and I were also flying kites. The kite we flew was a small "swallow" that we had just bought. Under my father's guidance, I held the spool in my left hand and the kite string in my right hand, and ran while releasing the string. Our "Swallow" flew up quickly and got higher and higher.

Just as I was admiring the swallows, I suddenly felt the kite string tighten in my hand. Ah, it was my Swallow that was going to fly higher and higher. I let go of the string immediately. As I let go of the string, I felt that the string in my hand was getting loose again. You know what? This is my little swallow telling me that it wants to stop and enjoy the beautiful scenery of Xi'an!

Suddenly, I felt the kite string shaking in my hand and wondered what my little "swallow" was going to do. At this time, an old grandfather told me: "Little friend, our two kite lines are entangled together." I was puzzled and asked, "How do you know that?" The old man told me so and so. Later, with my father's help, my kite strings were finally untangled. My little "swallow" flew smoothly and steadily again.

At this time, I told my mom that it felt good to fly a kite. Mom said, "There are many benefits of flying a kite! It is not only a way of entertainment, but also a kind of fitness exercise. It's good for moving one's limbs, improving eyesight, and preventing and treating cervical spondylosis and spinal disease." After listening to my mom's words, I love kite flying even more. In the future, as long as I have time, I will often come to South Gate Square to fly kites.
