Yuefu Miscellaneous Notes on Duan 'an Festival in the Tang Dynasty has the saying that "Kaiyuan Huang Zanchuo and Zhang Yehu joined the army". Zhang Yehu is a poet, Zhang Hui.

There is no golden millet shadow here, and the top of Yushan Mountain is still exposed in the distance. Climbing up, I suddenly saw the clouds rolling and the lake was full of waves. " After the founding of People's Republic of China (PRC), it was discovered by archaeologists that Chuo Mountain was a Neolithic site, with dozens of stone axes, chisels and pottery ding unearthed. 1983, the Cultural Management Committee of Kunshan County discovered 1 Jade Cong, which is a treasure, showing that Chuo Mountain has a long history.
