OP: Why couldnât traditional Chinese YinpiaoéśçĽ¨/silver drafts be forged if they were merely slips of paper? (cr大ćĺŽéďźć¸čś)
Traditional Chinese yinpiao/silver drafts were paper vouchers issued by private banks starting from the Song Dynasty(960â1279). People could exchange these slips for physical silver at bank branches across the country.
Silver drafts were made in multiple copies with matching serrated seal edges. One copy went to the customer and others stayed at the bank. All edges had to fit perfectly together to withdraw silver. The unique split edge marks were almost impossible to copy.
This mechanism is known as qifengéŞçź (split-joint seal) in China. It first originated in the Western Zhou Dynasty (1046â771 BC). The Rites of Zhou records that contracts were written on bamboo or wooden slips in duplicate. Notches and marks were carved in the middle before splitting the slips, with each party keeping one half. The two halves would be matched by their notches for verification.
During the Spring and Autumn and Warring States periods (770â221 BC), this idea evolved into hufuč珌/tiger tally tokens. A military tally was split into two pieces with identical inscriptions carved along the split edge. Troops could only be deployed if the patterns and characters on both halves perfectly aligned, serving as a metal version of the split-joint anti-counterfeiting system.
The technology matured in the Tang Dynasty (618â907). Government documents and private contracts commonly used split-joint seals stamped across the dividing line. The Chinese character "hetongĺĺ" (contract) was written across the middle before the paper was torn apart, so the complete characters would only appear when the two halves were put together. This split-coupon system was later adopted for Song Dynasty (960â1279) jiaozi paper money and yinpiao/silver drafts of the Ming and Qing dynasties (1368â1912).
Official Song dynasty paper money (Jiaozi交ĺ) was abolished in 1107. Private silver drafts issued by Qing-era piaohaoçĽ¨čĄ (ancient exchange banks) vanished completely in 1951, hit hard by modern banks and currency reforms. Nowadays silver drafts no longer circulate as currency. Their collectible value depends on their rarity and physical condition.
Split-joint seals (éŞçźçŤ qifengzhang)are still widely used on important paper documents in modern China, an anti-tampering technique passed down from ancient times. They are applied across the edge of multi-page contracts, bidding documents and official archives. If any page is removed or replaced, the broken seal pattern can prove the file has been altered.
OMG I got so excited about this because they used a really similar (though far less refined) version of this for contracts in the European medieval period!
First they were called "chirographs", but later the word "indenture" (in its earliest meaning as just a legal document of any kind between two people) came to be used, originating from the practice of a contract being written twice on a single piece of parchment and then cut in half with serrated edges (as in dent, "teeth" -> indents -> indenture) in order for each party to take one half, so they could later piece them together and verify that there had been no forgery -- same as the Chinese silver drafts!
(Charter of the ClerecĂa de Ledesma, 1252, showing the serrated indents at the top -- presumably they are cutting rather than tearing because they're using parchment, which I expect is much harder to tear than wood-pulp paper like the Chinese were using)
Delights me when human beings find similar ways to solve the same problem at two different ends of the world. <3
No points for guessing whose box.
u have GOT to be taking the piss abt mayodog nico boy
FUCK NO IM NOT ITS FUCKING GOOD MAYO AND KETCHUP OR NOTHING I AM THE GLIZZY GLADIATOR I HAVE THE GLIZZY TATTOO DO NOT COME AT ME NONE OF YOU UNDERSTAND HOTDOG LIKE ME

So I made this grain salad with my barley which was a neat idea except it turns out unhulled barley is BAD bad. So back to the drawing board. In a feat of the most foresight 20/20 I have ever had, I happened to make fresh chicken salad tonight with the leftover precooked chicken, so blessedly we had that to eat instead
Laughing looking back at this. #myInediblePurpleGrains
Thinking about Kata.
sometimes i forget there are linux users who don't know how linux works
I have been using linux for 20+ years and have several linux certs, and I donât know how linux works.
Its just âsudo rm -rf */â and bobsyeruncle, right?
The only thing you need to know about Linux is to be yourself and have fun

Went to a fabric store yesterday and saw a sewing machine that did embroidery of photos and the example was of a newborn baby and it was so fucking insane looking I asked an employee if I could buy it and she looked at it and was like âoh my god eugh what the fuck⌠i think thatâs my bosses grandkidâŚ.I think you should just take itâ so I did
Please someone tell me where i can get stupid embroidery patches made of my photos

the outdoor lights turned on because the wildfire smoke is so thick
i played a game as a kid called 3D Dinosaur, and i remember being very freaked out by the clip where the dinosaurs died after the meteor blotted out the sun with all the dust it threw into the atmosphere.
very cool to get to live a small version of that every summer now.
weirdly enough, the skies were a much creepier yellow-brown all day yesterday but the smoke wasn't as bad
very hazy blue skies today. DEFINITELY worse air quality. immediately smelled the smoke upon walking to my car this morning. at first (despite knowing it was probably the canadian smoke) wondered if somebody was burning a campfire. nope, just wildfire.
we're expected to get "hazardous" air quality later today.
