The rain avoidance period does not mean simply avoiding rainy days, but avoiding the "aura nodes" of alternating solar terms.
Purpose: To explore the growth proposition of people actively choosing to hibernate, face their hearts, and reconcile with the past when they are in trouble, confusion, and approaching storms. It conveys the humanistic core of "avoiding the wind and rain from the outside world and keeping inner peace", and has both a sense of folk atmosphere and realistic emotional resonance.
