The temperature difference between morning and evening is very large in summer resorts. Tiantai Mountain has profound historical and cultural connotations. As early as ancient times, Tiantai Mountain in Bashu was the place where the ancient "Qiong" people lived and multiplied. In the time of flood and famine in ancient times, when Dayu was passing through Shu State, he chose this mountain as a platform for celebrating the heavens, so he got the good name of "Tiantai".
