This is a period of qualitative change, where one feels weakened and powerless; new things have become old, facing challenges from other new things. Shuai (衰), after the previous stages of Changsheng (长生), Guandai (冠带), Linguan (临冠), and Diwang (帝旺), has reached the stage of decline in destiny, gradually going downhill, starting to decrease from large to small according to a certain standard. Analyzing the literal meaning of Shuai (衰), it implies the peak of prosperity followed by decline. In destiny, Shuai (衰) signifies depression, guarding one's life, indicating a lack of initiative, prone to despondency and frustration when encountering setbacks, attracting disputes, illness, financial loss, and decline during unfavorable periods. It metaphorically represents the decline of life energy, lacking the spirit and patience to overcome difficulties. Some prediction books describe Shuai (衰) as containing meanings of powerlessness, weakness, frailty, insignificance, depression, intellectual deficiency, downfall, small strength, misfortune, retreat, lack of support, weakness, timidity, fragility, short stature, incompetence, lack of skills, mediocrity, inability to resist, etc.

Generally speaking: In a BaZi (八字) chart with Shuai (衰), the manifestation is: conservative, mature, and not prone to compromise. Most experiences in life have been tried, and there is a certain level of experience, so such people handle matters more steadily, not flamboyantly, with resilience, and are easily satisfied. It is important to note that Shuai (衰) here is different from the concept of prosperity and decline in BaZi (八字), and is not the same concept.
