Historical evolution

Shimen town is located in the west of Langao County. According to legend, there was a monk carrying iron Buddha in his early years. At first, he was very light, but when he arrived at the place, he was too heavy to move. That is to say, he built iron Buddha temple here. Therefore, it was once called Tiefo. Later, it was renamed Shimen because of the two mountain walls at the junction of Hengxi River and Landa highway. In the Qing Dynasty, Langao was divided into four townships, East, West, South and North, with a total of 50 baos, and Tiefo temple was Xixiang.
