What's the lowest temperature in Beijing?

The lowest temperature in Beijing reached-15.5℃, and reached a new low this morning, reaching-16.4℃. According to experts from Beijing Meteorological Observatory, this is also the lowest temperature in Beijing in recent years. At this time last winter, the low temperature of-14.9℃ appeared in Beijing, which was the lowest value of 10 years before. This winter, since the temperature dropped from 1.9, the weather has been getting colder day by day. Today, it reached minus 16.4℃ for the first time, the lowest in recent years. At the same time, many years of meteorological data also show that the average temperature in Beijing in the same period last year was only -4.2℃, and the highest temperature during this period was more than 2℃ lower than the average temperature in the same period last year. This is somewhat doubtful. Since the end of the 1998 warm winter, is it getting colder and colder in Beijing?
