"Go Rixin, Day by day, Day by day" was engraved on the bathtub of King Tang of Shang Dynasty. It originally talked about the issue of bathing: if you wash away the dirt all over your body today, you must wash it off every day in the future. Wash away the dirt, and everyone must persist in this day by day. By extension, spiritual baptism, moral cultivation, and ideological transformation are not the same.
