Hello Beijing! What a difference a day makes! Yesterday, we enjoyed clear skies with temperatures ranging from 9 to 24°C, but today, our air quality has taken a nosedive into 'unhealthy' territory. We're starting overnight with lows around 11°C and highs peaking at just 24°C this afternoon. It's a clear night, but the air isn't exactly breathing easy! Looking ahead to tomorrow, prepare for a similar pattern with temps hitting 25°C while that pesky air quality remains in the unhealthy zone. Remember, just like our Great Wall, we must stand strong and not let these conditions knock us down!
