The first bomb shelter in Shanghai appeared during the War of Resistance against Japanese Aggression period. In order to avoid the enemy's artillery bombardment, Shanghai built some civil defense facilities to protect personal and property safety. With the passage of time, some air-raid shelters with low construction standards and a long history have leaked and accumulated water, causing the superstructure to collapse. For this reason, many urban areas in Shanghai have carried out centralized rectification of these air-raid shelters that have lost their air-defense functions, and explored and developed new functions on the basis of eliminating potential safety hazards.

No.212 Baotun Road is an emergency shelter. But after entering the gate and walking down dozens of steps, there is a public gym of several hundred square meters. The reporter saw in the gym that the aerobic and anaerobic equipment here is relatively complete and well ventilated. Just looking at the gym, I didn't think it was a bomb shelter.

The gym staff told the reporter that this gym belongs to the people's gym in Bansongyuan Community, and the surrounding residents usually come to exercise. Gyms are public welfare, and the price is cheaper than other gyms.

In addition to the civic gymnasium, an activity room of the community cultural activity center is also in the reconstructed air-raid shelter. Residents nearby can come here to perform, dance, perform and other activities. For Shanghai, a central city with precious land, such public service places meet the physical and mental needs of many citizens.

After hundreds of air-raid shelters have been renovated, the Technical Standardization Research Office under Huangpu District and Shanghai Municipal Bureau of Technical and Quality Supervision will issue the Construction Standard for Disposal of Abandoned Civil Air Defense Projects this year, which will be strictly implemented to renovate more air-raid shelters under historical buildings.
