Du Pengcheng's classical Chinese article, Walking in the Spirit Palace Gorge at Night, was as follows: "Walking in the Spirit Palace Gorge at Night" Du Pengcheng entered Linggong Gorge at night. One after another, iron fences were set up, as dense as woven nets. He walked along the mountain road and occasionally encountered some obstacles, but he always relied on his intelligence and courage to successfully overcome the difficulties. Finally, they arrived at the deepest part of the Spirit Palace Gorge. There was a towering mountain peak that reached into the clouds. On the mountain peak, there was an ancient temple. The door of the temple was tightly closed, and there was a sign in front of it that said,"No entry is allowed at the entrance of the Spirit Palace Gorge." Du Pengcheng felt uneasy. He didn't know if there would be any danger in this temple. However, he still decided to go in and take a look, hoping to find some clues. He pushed the door open and walked in. He saw that the temple was filled with all kinds of cultural relics and offerings. He walked slowly and carefully observed these artifacts and offerings, hoping to find some clues. Suddenly, he heard a faint sigh. He couldn't help but feel curious and went forward to ask. Then he found a young woman crying and looking very sad. Du Pengcheng sympathized with the woman and walked over to ask her why. The woman told him that her father had been murdered and that she was looking for the murderer but had not found him. After Du Pengcheng heard this, he thought of an old friend who had helped him solve many problems. So he decided to help this woman find the murderer. Du Pengcheng and the woman walked out of the temple and arrived outside the Spirit Palace Gorge. He told the woman that he would help her find the murderer. The woman was very grateful after hearing it.
