September 19, 2020 shenzhen, china tested the air raid system. Sorry for the background noise. I was standing on a city street on a rainy day and the cars made a lot of noise driving through the wet streets. I'm not sure if they do this test every year but i do remember they did it last year. I'm also not sure if this is province wide (guangdong) or maybe even country wide. The government let us know about a week earlier that they would do the test. If they let me know one day or even better one hour before the test, i may have been able to get to a quieter area for a better recording. There were some tests earlier with longer tones but my recording had even more background noise and this was the best one.
