When will the soil be forgotten?

Does the subject want to ask "when is the king of the earth" in the first nine days and the last nine days of March, June, September and December? March contains the atmosphere of Tomb-Sweeping Day and Grain Rain, so the first nine days and the last nine days and the eighteenth day of Grain Rain are the days when the soil is rich in spring. June includes the light summer festival and the great summer heat, so the first nine days, the last nine days and the eighteenth day of the great summer heat are the most prosperous days in summer. September is the cold dew festival, and the first frost is full of breath, so the ninth day and the last nine or eighteen days of the first frost are the most prosperous autumn festival. December is a slight cold festival, which is very cold, so the first nine days, the last nine days and the eighteenth day of the great cold are when winter is booming.
