  Ming Qin King Zhu Xia was Zhu Yuanzhang's second son. The Ming Qin Palace was his mansion, and the southern wall was part of his mansion wall. In 2003, the ruins of the walls of Ming Qin Palace was listed as a key cultural relics protection unit in Shaanxi Province.

  Wang Wei, vice president of the Shaanxi Provincial Cultural Heritage Research Institute, said that this section of the collapsed area was the restoration and protection of masonry in the western section of the southern wall of the Ming Qin Palace, not the Xi'an City Wall, a national key cultural relics protection unit. Before the collapse, relevant local authorities had set up a cordon on the site in accordance with the regulations and prepared to enter the site for reinforcement after the rain.

  A reporter from Chinanews.com learned that in September 2019, the wall of the Ming Qin Palace was flooded. According to local media reports, the cause of the flooding disease was the settlement and cracking of the sea block on the top of the city wall, which caused rainwater to penetrate the soil of the city wall; the expansion of the soil caused the brickwork on the north side of the city wall to move outward. At the east end of this section of the wall, sporadic soil blocks slipped and water seepage disease appeared on the waist of the north wall. At that time, relevant departments formulated temporary protection measures such as supporting a simple rain shed on the top of the city wall, adding a fence at the bottom of the city wall and assigning special personnel to patrol, and sticking plaster strips to the existing wall cracks.

Emergency repair, foundation reinforcement, wall crack repair, and emergency reinforcement of another section of the city wall.

  According to Chen Ping, a professor at Xi’an University of Architecture and Technology, after site surveys, it was determined that the total length of the repaired and protected masonry on the western part of the southern wall of the Ming Qin Palace Wall Site was more than 130 meters, and the collapsed part was about 20 meters long. The collapse was directly caused by the recent continuous heavy rain. The collapsed part is the newly built protective soil body of the original city wall site and the outer brick masonry on the northeast side, which did not damage the original Ming Dynasty city wall rammed earth.

  At present, the local cultural relics department has organized an expert group to conduct survey and consultation, and formulate a dangerous situation disposal plan to strengthen and restore the protective layer. According to the opinions of the expert group, the collapsed soil and blocks in the collapsed area on the north side will be cleaned up in time, the corresponding protective masonry in the collapsed area will be partially unloaded, the seepage range and depth will be surveyed, and temporary rainproof and protective measures will be taken for the removed parts .

  At present, a dedicated person has been arranged for 24-hour monitoring on site. At the same time, the cultural relics department is conducting a comprehensive investigation of cultural relics protection units in Xi'an. (Finish)
