It’s Chinese New Year so they’re taking longer holidays and shutting down public spaces as a precaution and as part of the three week long festivities
Don’t be so fucking ridiculous.
Not sure who you think is being ridiculous. The New Year/Spring holiday dates in China are 24th - 30th Jan (inclusive). The government, and subsequently all employers, announced yesterday (or was it the day before?) that the holiday had been officially extended to 2nd Feb. I work for a Chinese company and nobody shuts down for 3 weeks, 2 is fairly normal for some manufacturing industries, and many many workers who have to travel a long way back to their families simply leave their job, then go back to a new one after a couple (or three or more) weeks away.
Companies, under government supervision, are taking precautions such as telling people to stay home if they have, or think they have symptoms, and although people are reporting not being able to buy medical masks in shops, most big companies have bought a massive supply to distribute to workers and their families.
My colleagues are reporting that some places are shut down, some big celebrations were cancelled and people, especially susceptible ones (old, young, pregnant etc) are being recommended to stay home. Mostly they're reporting that they're bored already.
