Introduction to the ancient city wall: Snake up from the intersection of the cliffs of Qishan and Gushan, you will find the entrance to the unique ancient city of Yueyang. The entrance to the mountain is steep and the road is narrow, and one man can't pass it but ten thousand men can't open it. The ancient city walls are all made of stone, built around the entrance of the village, and are more than ten meters high to resist invading enemies from the bottom up. There are ancient military training ground, military parade platform and the official residence of the Shanzhai King in the city. The stone gate used by the volunteers to block the entrance of the village and the stone mortar used for grinding rice are still intact. Legend has it that Tang Kuang rebelled and occupied the stronghold as king. The officers and soldiers went to suppress the stronghold and stayed under it for a long time. Tang Kuang was suspicious of the officers and soldiers, so he ordered some volunteers to go to the entrance of the ancient city every day to make loud noises and capture the pigs on the stronghold and howl at them. As expected, the officers and soldiers below the stronghold fell into the trap, thinking that the soldiers on the stronghold had enough food, so they killed pigs and drank wine all day long. Later, the officers and soldiers retreated and kept secretly. They dressed up as ordinary people and plowed and sown in the fields. They collected pine leaves from the mountains and used them as seedlings to plant in the fields. When Tang Kuang saw that the people in the village were living and working in peace and contentment and farming according to time, he mistakenly thought that the officers and soldiers had retreated. , he personally went to the stronghold to investigate. He held the two gates with both hands and glided down from the wall at the entrance of the stronghold. He was captured alive by the officers and soldiers who were pretending to plant crops in the fields.
