The Pandemic in China - What Are the Pop-Ups?

Three years into the pandemic, people's frustration have just reached a peak. We don't really have any energy or spare time to think about how other people are doing worse than us. I was actually a direct victim of that. Back in the beginning of the month, I was on a reporting trip to Juhai to report the air show. And around the third day I was there, I got a pop-up window on my Beijing house codes mysteriously. So, it seems that Beijing is facing quite a similar situation to what we saw in Hong Kong last January.
