In July 2017, a Jin Dynasty tomb was discovered at the construction site of Huayao City in Handan. After cleaning, a large number of wall paintings were found in the tomb. Since wall paintings are not often found in Handan, this discovery is of great significance for the study of the history and culture of Handan. Therefore, the preservation of the actual wall paintings is very important and necessary. Following the procedures of cultural relic conservation and restoration regulations, conservators cleaned up, pre-reinforced, reinforced, divided, supported, cut and moved the wall paintings. The wall paintings of the tomb were divided into 17 pieces and all of them were transported back to a warehouse for cultural relics. The subsequent conservation and restoration work began in June 2020. The bricks were subject to secondary polishing and cutting, desalination, reinforcement, flipping, cleaning, completion and coloration. The conservation and restoration work of these wall paintings was successfully accomplished.
