It's a Jewish holiday, and it falls in the month of Tishrei, on the 15th day. Also a harvest festival, commemorates when the Jews left Egypt and they wandered through the desert for 40 years, and they built these sukkahs, or booths, sort of these huts throughout the desert, and slept in them. Now, how that's translated to modern times is people will build a sukkah or a little hut or booth, usually in their backyards. When you grow up in Hong Kong, like my kids did, or in New York City, where I was before, most people don't have a backyard. We live in high rise buildings, so for us, it's a communal sukkah that's built, and everybody sort of has a hand in decorating it, and it's just decorated really, really, really beautifully. And also, there's the four species, which is mentioned in Torah, and all of those are brought together. The four species are the lulav and the etrog. And the lulav is like a palm branch, and it's combined with a myrtle and willow and then they're bound together, and then held together with the etrog, which is like a citron, sort of like a lemon. You take the lulav and the etrog together, and there's a bracha that you say, so a prayer that you would say, and you wave them east, south, west, north, up and down. You need to also be able to see the stars from the sukkah. So when you build this hut, it's built not with a roof, and it's meant to be sort of impermanent. There's branches or leaves on the roof so that you can still see the night sky, which is also an important part of Mid-Autumn Festival. So the festivals just really, really, just work together in a beautiful and sort of natural way.
