Level 7 was used for accommodation of hotel and car showroom workers. The roof contained a 40 sqm office used by the owner of the building, the lift motor room, 4 plastic water containers and one stainless  steel water container. Collapse. At 19:14 on 7 March 2020, the Xinjia Hotel suddenly collapsed. A witness said that he had heard a big bang from the external tempered glass of the hotel. He then witnessed the whole building collapsing within a few seconds. An employee of the hotel stated construction work had been done to the structure's foundation. Rescue. About 70 people were trapped in the collapsed hotel. After the collapse, Fujian Fire Brigade sent 26 fire engines and 147 firefighters to rescue the victims. 32 victims had been rescued by 21:50 that day. At 22:14, Putian Fire  Brigade arrived at the hotel. At least 47 victims had been rescued by 8 March 2020. On 12 March 2020, all the 71 victims, including 29 dead bodies, were rescued. Investigation. The police started an investigation concerning Mr. Yang, the proprietor of the hotel. On 10 March 2020, Shang Yong, the vice-minister of the Ministry of Emergency Management of People's Republic of China, stated that this incident was relevant to the responsibility for safety in production, and he also stated that the incident would be investigated entirely and legal responsibilities would be pursued. On 12 March 2020, the  State Council of the People's Republic of China announced establishing a team to investigate the collapse, and appointed Fu Jianhua as the team leader. The results of the investigation, published in July 2020, revealed that the owners had in May 2016 had added floors within the building, adding a total of 2 extra floors, which raised the load on the building slightly past its limit at 52100 kN, 100 kN over the design limit. When converting a ground floor supermarket to a restaurant on 10 January 2020, 3 supporting columns were found to be seriously deformed, though due to  the Chinese New Year, work had not yet commenced until 1 March, where 3 more columns were discovered to be deformed. The repair works commenced on 5 March, with works done on 5 columns leading up to the collapse, with one column yet to have been repaired. However, the investigation reveals that the welds were not close enough to the next floor, leaving too large gaps between the welds, resulting in the welds providing no additional support, and is concluded to have worsened the deformation of the columns, resulting in the collapse.
