About 30km southeast of Qūfù, this cave on Ní Shān (尼山) is where, according to legend, a frighteningly ugly Confucius was born, abandoned and cared for by a tiger and an eagle before his mother realised he was sent from heaven and decided to care for him. The gravitas is a bit hokey, but the sight offers a chance for some fresh air.
Buses for Ni Shān (¥8) leave regularly from the long-distance bus station. A taxi there is about ¥40.
