Yongle Palace, built in Yuan Dynasty, is located in Ruicheng County of Yuncheng, a city in north China's Shanxi Province. The total area of murals preserved there is more than 1,005 square meters.

Workers have completed the digital collection of the murals, monitored and analyzed the surrounding temperature, humidity, and carbon dioxide level before the restoration began, said Xi Jiulong, head of Shanxi's Yongle Palace mural preservation research institute.

The restoration and protection work is expected to be completed in three years, Xi confirmed.
