Introduction to the Tongque Terrace ruins: Tongque Terrace is the main platform of the three. Built in the 15th year of Jian'an, the platform was ten feet high and had hundreds of rooms. After the platform was completed, Cao Cao ordered his sons and other scribes to go on stage and compose poems. During the reign of Zhao Shihu, the height of the platform was increased by two feet on the basis of the ten feet high, and a five-story building was built. On the top of the building, a bronze bird with a height of one foot and five feet was placed. Wrapped around the waist of the stage, it is known as the beautiful scenery of "bronze bird flying into the clouds". In the late Sixteen Kingdoms period, the buildings on the platform were in ruins. In the Yuan Dynasty, a corner of the Tongque Tower was washed away. Most of them were washed away by water in the late Ming Dynasty. Now there is a southeast corner left on the ground, sixty meters long, twenty meters wide and five meters high.
