Has there ever been a safety accident in the South Community of Apple Community in Chaoyang District, Beijing?

Underground civil air defense space has been flooded for a long time. According to the website of the Chinese People's Political Consultative Conference (CPPCC), the third floor of Buildings 5, 7 and 9 in the southern district of Apple Community has been leaking and soaking water all the year round since the community was completed. It is observed that the frequency of treatment is not high, and it is not timely, which leads to the fact that civil air defense projects are often in a state of soaking in water for more than ten years.
