This folk proverb refers to the day when the Dragon King, who is in charge of heaven and rain, wakes up and raises his head on the second day of the second lunar month. After that, the private rainfall will gradually increase, which can replenish the water and nutrients needed for crop growth in time, which has played a very good role in promoting this year's harvest, indicating that this year will be a bumper harvest year. In fact, it is of little significance to explore the truth and falsehood of this proverb, because it is just a good wish of working people for a good weather and a happy life in their daily work and life. "Barn" refers to the barn. Everyone eagerly hopes that the barns, large and small, will be filled with rice and even flow out of the barn. This is an expression of everyone's inner desire.
But in detail, "February 2, the dragon looks up, the big warehouse is full, and the small warehouse flows" also makes sense. Working people in farming society depend on the weather for food, and the weather is very important for the growth of crops. On the second day of February, around the vernal equinox of the 24 solar terms, it is also an important moment for everything to revive and seeds to germinate. At this time, only abundant rain can make the seeds germinate completely and farmers can start farming in the new year. Therefore, in the eyes of the public, the rise of the dragon in February indicates a lot of rain, which means a bumper harvest this year.
On the endless grassland, the four seasons come and go, and the change of the four seasons is a natural law. After many years, the argument has its own truth. We should still have admiration for "February 2, when the dragon looks up, the big warehouse is full, and the small warehouse flows".
