It's not bad here yet either. Stuff is closed down but you can still take the subway. Theres probably a hundred communities shut down city wide but that's likely just a fraction of a percent of all communities. But, the number of cases do not stop increasing, so lockdown will certainly come in the next few weeks.
Most likely, but even among districts the actions they take are different. Our old neighborhood (in Chaoyang) has benn closed multiple times. Here in Dongcheng we have only seen that in 2020 during February till April, though 'lockdown' and no classes had been till the new semester in September. We will see what happens. Anyways, best of luck. Stock up on food and work from home. Luckily for n our family we can easily.
