What is the pronunciation of first frost?

Note: In Gregorian calendar 10 year, one of the 24 solar terms is1October 23rd or 24th. At this time, the first frost generally appeared in the Yellow River basin in China, and most areas were busy planting crops such as wheat and wheat. Yizhoushu Zhou said: "Autumn and March are empty: summer, autumn equinox, first frost." "Mandarin Zhou Yuzhong": "See the fire and cool breeze to stop the cold." "The History of the Three Kingdoms Wu" notes: "As the saying goes, after the first frost, the breeze comes first, and people should have a cold heart." Wei Wei's "Oriental" Chapter 15: "In the solar terms, there are several frosts here before the first frost."

For example, when the cool breeze goes hand in hand with the autumn rain, when the yellow leaves hold hands with the morning frost, when the blue borders with the gold, the warm season floats by, autumn comes, and the weather is cool, which is the first frost day. Greetings: Pay attention to your health!
