Yinde
It means 'accumulating virtue in secret'; traditionally, it was a day for granting kindness, righting wrongs, and redressing injustices.
Refers to virtue accumulated through secret, unpublicized acts of goodness. Traditionally, Yinde is considered a deep source of blessings; its power comes from good deeds done without seeking reward. Therefore, the Tong Shu (almanac) often marks days with 'Yinde' as auspicious, suitable for performing quiet, non-public acts of goodness—such as secretly bestowing favors, helping others redress grievances, or making charitable donations without publicizing them. Such actions are believed to accumulate profound blessings, and their influence is often more enduring than that of publicized good deeds.
