Introduction to the Central Pavilion: The Central Pavilion was built in 1906. It is a three-bay Chinese-style bungalow with a two-story spire building on top. It was originally called the Meteorological Institute, used to predict weather. It is the location of China's earliest meteorological observation institution. Later, the test center was moved and the central hall was converted into an exhibition room for epigraphs and inscriptions. Mr. Zhang Jian personally inscribed the plaque on the central hall.
