This footage was filmed and produced 18 April 2023.

This footage shows an old arch crown kiln complex in Changjiagou village, Zhangjiakou city, North China's Hebei Province. Arch walling kiln is different from the arch walling kiln in Shaanxi, Shanxi and other places, which is embedded in the mountains near the cliff, but built with brick, stone and soil into a curved base and built on the ground. Arch walling kiln has a history of over 1700 years and was once a common dwelling in the area. However, with the popularization of modern housing construction and the advancement of urbanization, arch wadded kiln which has been vacant for a long time has been seriously damaged due to disrepair.
