Qufu's main business is the Kong family legacy — the Three Kong Sites (Temple, Mansion, Forest) that are the UNESCO-listed core of the city. Beyond these, the walled old city contains the Temple of Yan Hui (Confucius's favourite disciple), a functioning Mosque, and the Mausoleum of Shaohao (a legendary pre-dynastic emperor) on the eastern outskirts. September's birthday festival for Confucius is the most significant annual event, drawing pilgrims and scholars from across the Confucian world.
