Great sharing! In North America churches often time will host Harvest Carnival/Festival on Oct 31st as an alternative of Halloween/Trick-or-Treating for kids...
Just look at bossini x M&M'S 萬聖節服飾, a line targeted for Halloween, with all the cute M&M characters on it... well target for kids.
When I look at Halloween, sometime I compare it is just like Christmas. We (Christians) celebrate Christmas, while Jewish cannot. They can only celebrate Hanukkah.
