It was written by Bai Juyi, who suffered from cataract.
Someone performed acupuncture cataract surgery in the Tang Dynasty in China, but Bai Juyi, a famous poet, had poor eyesight. He described this in his poem.
The symptom of writing about yourself is "a thousand pieces of snow are scattered, and a heavy yarn is put on the cage." It's like watching fog on a sunny day, not blooming in spring. "He also tried to treat it in other ways:" The case was full of dragon tree theory, but the pill for storing cassia was empty. "
If all the prescriptions in the world are useless, I'm afraid we'll have to "try scraping" with the needle-removing technique. Even if it is an "incurable panacea", it can also "sweep the sky with a golden needle" after the operation.
Ancient records of cataracts
"The Secret of Outer Taiwan" Volume 21: "The eyes start for no reason, and suddenly there is a film, which is painless and gradually unclear. A few years later, it became blind, which made the eyes look the same, but in the center of the eyes, in the beads, there was a barrier, which was blue and white. Although it doesn't distinguish between things, it still knows light and darkness, and it knows day and night. If there is, it is called talent flow.
