Old people often say: good years, sad spring, what exactly does it mean?

Chinese new year is just a symbol of prosperity for a few days, and spring is a time when green and yellow are not connected. This used to be the worst time of the year, because this year's grain was just planted, and last year's grain was used as seeds, and there was not much left, even to the point where there was no food, so only the elderly had such a saying, because this phenomenon no longer exists.
