Well…it still is here, anyway 
Always celebrated this holiday as a child and never really knew why (back then). To this day my fam exchanges Double-Ten Day greetings.
Kowloon, Hong Kong: Lion Rock, 2009
Enjoy what’s left of it SauLan!
Have to say, seeing all the mad throngs swarming around CKS and districts yesterday with fistfuls of flags and flag-themed gear (the Government did a big push this year to deploy massive quantities of giveaways, apparently), was pretty heart-warming.
The display of (ostensibly) non-partisan patriotism was something we rarely get to enjoy.
My fave was the kid waiting for the bus on SongRen with the full sized flag tied around his neck and hanging down his back like a superhero cape. 
CKS died in '75, so why is this in religion?
I was also wondering why this would be in the religion forum. Anyway, I kinda feel scammed. I was on the island for the last two double tens and they weren’t counted as holidays. I had to work! I don’t like the flighty way Taiwan decides what’s a holiday and what’s not. I like double ten day. It’s my third favorite Taiwanese holiday. When it’s a holiday. Mid-Autum Festival is my favorite and I just got to miss that one again, too. 
I think it’s just SauLan’s favorite forum 
It could be considered para-religion or implicit religion (like Confucianism, Soviet Communist lore, or the U.S. “civil religion”). Have you not heard that Taiwan is the “sacred” territory of the PRC?
Sorry guys, feel free to move it or delete it or whatever. I grew up in HK where anything number-related is religious lol. For us it always just had mysterious connotations of astrological fortune. Perhaps a false extrapolation from the ever-present Double Happiness. I did become aware of the Taiwanese connection, though, when some students squabbled over putting a flag on High Junk Peak, but initially as a kid I thought they only planted the flag because they happened to have the day off–since of course it was Double Ten Day
