Grade 5-6: 1 vertical bar, 3 horizontal bars.
Grade 7-8: 1 vertical bar, 4 horizontal bars.

Precautions:
In fact, in nature, the wind sometimes exceeds 12. For example, the central wind force of a strong typhoon or tornado may be much larger than the magnitude of 12, but the wind above the magnitude of 12 is rare, so the magnitude is generally not specified.
In the weather forecast, we often hear the expression "the north wind is 4 to 5", in which the wind refers to the average wind; If you hear the expression "gust 7", gust refers to the wind with high and low wind speed, and the wind at this time refers to the maximum wind force.
