The reporter learned from the Henan Provincial Institute of Cultural Relics and Archeology that the National Social Science Fund Project "Comprehensive Research on Cao Cao Gaoling and Mausoleum" published new research results. The foundation site of the Song and Yuan Dynasties was found on the west side of Cao Cao Gaoling, which may have been set up for Cao Cao Gaoling in the Northern Song Dynasty. Where is the tomb guard.

　　The north-south ditch-shaped relics discovered by exploration were confirmed to be a drainage ditch after excavation.

The proven total length is 160 meters, and the excavation area covers a length of about 40 meters in the middle.

The east and west walls of the ditch are inwardly inclined, and the bottom is an arc bottom, with a width of 7-9 meters and a depth of 2.1-3.8 meters.

There is obvious alluvial soil at the bottom of the ditch, and the upper accumulation can be divided into three layers, containing a large number of porcelain pieces and other relics.

It shows that this ditch should have been used as a drainage ditch at first, and it was gradually landfilled by domestic garbage after it was abandoned.

　　The unearthed relics in the ditch are very rich, including pottery, porcelain, bone, bronze and other materials.

Among them, porcelain is the main one, and there are 899 complete wares or utensils that can be repaired.

The drainage ditches revealed by the excavation only account for a quarter of the area (about 40 meters in length) of the proven remains. The large number and richness of the unearthed remains are very surprising.

Most of the unearthed porcelains are bowls, plates, plates, pillows, pots and other daily-use wares, including white porcelain, black glazed porcelain, Jun porcelain, celadon, white ground and black flowers, etc., and also include products from Ding Kiln, Jun Kiln and Cizhou Kiln , across the three dynasties of Song, Jin and Yuan.

　　The discovery of a large number of Song Dynasty coins and entertainment equipment shows that there used to be public entertainment activities here.

Combined with the characteristics of the architectural relics unearthed in the ditch and the characteristics of the associated drainage facilities, archaeological researchers speculate that the buildings existing here may not be ordinary dwellings, and may have some official attributes.

The age of the unearthed porcelain suggests that these related buildings may have been built in the early Northern Song Dynasty and continued into the Yuan Dynasty.

The changes in the shape and craftsmanship of the utensils indicate that the function of the building has obviously changed many times in the three different eras of the Song, Jin and Yuan Dynasties.

Most of the exquisite utensils and entertainment tools are from the Jin Dynasty, reflecting the frequent public entertainment activities here during this period.

　　According to comprehensive research, the architectural remains found on the west side of Cao Cao's Gaoling are likely to be related to the mausoleum guards set up in the Northern Song Dynasty.

After the Song royal family moved south, the Central Plains area was successively controlled by the Jin people and then the Mongols. The Shouling House, the last witness of Cao Cao’s Gaoling, may have been abandoned and the original buildings were repurposed for other purposes.
