Halloween English is AllSaintsDay, also known as "all saints' tribute", one of the Catholic and Orthodox festivals, and a traditional festival in western countries. Chinese-speaking areas often mistake Halloween for Halloween. "Hallow" comes from Middle English halwen, which is very close to the etymology of holy. In some areas of Scotland and Canada, Halloween is still called "AllHallowMas".

On that day, the Mass ceremony to be held is to celebrate all the saints in heaven. Nowadays, for commercial interests or other purposes, all kinds of activities full of monsters are organized on the night of1October 3 1 day, which completely deviates from the sacred significance of Halloween.
