The Ming Temple was built on the site of Jiao Hutai. Jiaoyutai, commonly known as Cao Cao Point General Tai, is located in the old urban area of Hefei, south of Xiaoyao Gujin, and is separated from the park. The platform is over 5 meters high and covers an area of more than 4000 square meters. The platform is as steep as a castle. In the late Eastern Han Dynasty, Cao Cao visited Hefei four times to command on the battlefield, "Jiaoqiang crossbow 500" to snipe the water division of Dongwu, so he called Jiaoqiutai, which has a history of more than 1700 years. The teaching crossbow was originally outside the old city. During the Song Dynasty, the Hefei city was expanded and the site was enclosed in the city. Since then, Hefei City has experienced countless storms, but the teaching crossbow has always stood up, and has become the historical witness of the rise and fall of Hefei.
