What's interesting in Xuzhou?

The number .........., if you have to say it, is nothing more than Peng Zu Garden, Quanshan Park, Jiuli Lake, Guishan Han Tomb, Su Causeway, Huanglou, Circus Stage, Hefangting and Yanzilou. Kuaizai Pavilion Qijiyuan, Chu Tomb of Lion Mountain, Huaihai Campaign Cemetery, Wang Jie Martyrs Cemetery.

. It looks a lot, but it's not interesting.
