The film adopts a tender and affectionate way of telling, closely combines the real theme, takes "a letter" as the starting point, and shows the topic of "caring for parents" through stories that happen around us. Talking about the original intention of creation, the master plan of A Letter from Mom said: "Modern people's lives are very busy, and many young people are working hard for their careers outside, which will inevitably ignore their care for their parents. Caring for the elderly requires the participation of all sectors of society. " He said that although the whole film was only 10 minutes, all the crew members did their best. Whether recruiting actors or preparing for filming, everyone is enthusiastic and actively involved, hoping to light a beacon of public welfare for the society through their meager strength. The film aims to show some fragments of life, so that everyone can understand that material care for parents is important, but spiritual care for them can not be ignored. Love for parents is not necessarily living in a mansion, finely decorating, and taking time out to spend more time with parents, but visiting them often at home is a kind of care and an expression of love.
