Introduction to Caoxi Temple: In Anning Hot Spring Scenic Area, there is Caoxi Temple, a thousand-year-old temple built during the Zhenguan period of the Tang Dynasty. The temple is located in the Congshan forest about 5 kilometers northwest of Anning City, separated from the hot spring by the Mantis River. The wooden beam and column structure of the main hall is a typical Song Dynasty architectural style. According to the appraisal of the famous architect Liang Sicheng, the beam-column structure of the main hall of Caoxi Temple uses the bracket as the fulcrum, and the mechanical calculation is accurate. In the main hall, there is a magical landscape "Tiandong Baoyue" that cleverly combines astronomy and architecture. There is a garden hole under the eaves in front of the hall, about 30 centimeters in diameter. It is said that every Mid-Autumn Festival night in the 60th year of Jiazi, the bright moon passes through this small hole, and the moonlight directly shines into the precious mirror on the forehead of the Buddha statue of Sakyamuni. The moonlight is reflected by the precious mirror and shines on the ground. As the bright moon slowly Rising slowly, the moonlight gradually descends along the bridge of the Buddha's nose and ends at the Buddha's navel. This wonderful scene is called "Tiandong Baoyue", "Moon Reflects Buddha's Belly", also known as "Caoxi Temple Reflects Moon". Indescribably wonderful. It reflects the scientific achievements of ancient Chinese architecture and astronomy.
