The Eastern Qing tombs at Zunhua: five emperors in one valley
At Zunhua in Tangshan, a valley of 80 square kilometres holds the tombs of five Qing emperors, fifteen empresses and 136 imperial concubines, laid out along paved spirit ways and enclosed by mountains. The complex was inscribed with the Western Qing tombs in 2000, and its underground palaces are why it is studied.
