Introduction to Wenwu Square Gate: Wenwu Square Gate is the main entrance of Xiaoling Mausoleum. It originally had 5 door openings, 3 large and 2 small, with 3 arched door openings in the middle and 2 rectangular door openings on both sides. The roof of the veranda is covered with yellow glazed tiles. During the Tongzhi period of the Qing Dynasty, it was rebuilt into a doorway with a Qing stone gate inlay and the three characters "Ming Xiaoling" in regular script inscribed on it. It was renovated in 1999 and restored to its original appearance during the Ming Dynasty. It now has five doors, with yellow tiles, red doors and red walls. A rectangular door is hung above the main door, with four large gilt characters "Civil and Military Square Gate" written vertically. There is a "Special Announcement" stele on the east side of the main entrance. This stele was erected in the first year of Xuantong of the Qing Dynasty (1909). It is written in the Six Kingdoms script and warns about the precautions for protecting Xiaoling Mausoleum. There were originally two imperial pavilions built behind the stele pavilion, the west one was called the Sacrifice Pavilion, and the east one was called the Gufu Hall.
