Long ago, in a remote valley, lived a girl named Xiaolian. From a young age, she was fascinated by the stars in the sky and longed to one day touch them. She heard that on the highest peak of the valley, there was a path leading to the heavens, a winding and treacherous path that only the bravest and most determined could successfully reach the summit. Xiaolian was determined to try this path, believing that as long as she persevered, she would surely realize her dream. So she began the arduous climb. She climbed upward, one step at a time. When she encountered steep cliffs, she used vines and rocks to slowly climb upwards; when she encountered dangerous peaks, she used all her strength to climb upwards; when she encountered violent storms and rain, she hid in caves and waited for the storm to pass. During the climb, Xiaolian experienced countless difficulties and challenges, but she never gave up. With her perseverance, she overcame one difficulty after another. Finally, she successfully reached the summit, where she saw an incredibly magnificent world. She had realized her dream and touched the stars in the sky. From then on, people called this path the “Path to Heaven”, and Xiaolian’s story became a popular tale.
