As for the use of Tongque Terrace, it is recorded in Volume 5 of Shui Jing Zhu, Turbid Zhangshui, that in the northwest corner of Yecheng, the Terrace is ten feet high and there are more than 100 households. Wei Wu is looking forward to serving Wang Shuzhi. Chae Yeon rebelled and attacked the city gate. When Wang Xiu heard of the change, he led his men to the palace gate to help. Cao Cao saw it on the bronze sparrow terrace and said, "When he comes, it belongs to Wang Shuzhi." (Uncle Wang Xiuzi) According to this record, Tongquetai is not only a place where Cao Cao and his guests dine and write poems, but also a place to prepare for war.
