What are the minimum and maximum temperatures in the weather report?

Meteorology, 20 o'clock every day (Beijing) is the boundary of a day, that is to say, from 20 o'clock today to 20 o'clock tomorrow is a day. However, the daily maximum temperature refers to the temperature from 02:00 to 02: 00. When the daily maximum temperature is observed at 02: 00, the meter is adjusted (that is, the maximum temperature table is restored), and the daily minimum temperature is the lowest temperature value within 24 hours of 14. When14 is observed, the meter is adjusted. Usually, the daily maximum temperature will appear in the daytime, mostly in the afternoon, and the minimum temperature will usually appear at night, mostly in the middle of the night, but there are also unusual times, especially when cold air invades or the temperature suddenly rises sharply, and the time of occurrence is different.
