This statement comes from the classic "Buddha said the Koran". Legend has it that Mulian, a disciple of Sakyamuni, saw her dead mother become a hungry ghost in hell and asked the Buddha for help. Sakyamuni asked him to prepare Baiwei Zhai on July 15 to support monks from all directions and surpass his suffering mother on the road of hungry ghosts in hell with the strength of a monk. Manglietia Manglietia crossed over for her mother on this day, and Buddhist monks also helped Manglietia Manglietia to recite the scriptures for her mother, so that she could get out of her misery.
Later, Buddhist believers had the habit of offering sacrifices to their dead ancestors on the fifteenth day of the seventh lunar month to comfort and honor their living mothers.
The second Sunday in May is Mother's Day all over the world, so it's obvious that it's not about worshipping foreign things, and there's nothing wrong with learning good things from western countries.
