How to treat Beijing PM2.5 off the chart?

After all, the smog in Shanghai is somewhat different from that in Beijing. Although the taste of Shanghai is layered, it lacks the momentum that Beijing has, and the mellow old ash. Although Shanghai's pm2.5 has a smaller gas field, it is more bourgeois, and it is also pm2.5. Beijing is closer to pm3 and Shanghai is closer to pm2. If you insist, it is a hearty feeling to use a copper pot and make exquisite and interesting coffee with cat excrement. The smog in Guangzhou is humid and beautiful, but it is generally not as good as Beijing in terms of quantity and taste. I've also heard that the smog in Hebei is unrestrained, but it's a pity that the details are a little less. Personally, I think smog is still about accumulation. Compared with the smog in other places, I prefer the mellow smog in Beijing. It is so real and concrete. The sweetness of the soil is fully mixed with the fierceness of heating emission. Coupled with the catalytic effect and low pressure of tail gas, the smog tastes palatable and hangs in the lungs for a long time after inhalation, making the tasters want to burn. This is the crystallization of human hard work and talent ... the fog is thicker elsewhere, and the smog is pure alcohol!
