This ring lets blind people read non-Braille books
One of the problems with Braille is that it’s typically printed in specialist books aside from the copies created for sighted people, meaning that those with sight difficulties can’t borrow their friends’ books and need to seek out the bookstores and libraries that cater for them.

China has 8 cities with bigger bike share systems than all of America | Vox
The growth of bike share programs is gaining momentum in the US. But this growth is absolutely dwarfed by the explosion of bike share programs in China over the last couple of years. The country now has more than 400,000 bike share bikes in operation across dozens of cities with programs, with the vast majority installed since 2012. To put this in perspective, there are an estimated 822,00 bikes in operation around the world — so China has more bikes than all other countries combined. The individual country with the next-highest number of bikes, France, has just 45,000.
