The most interesting thing is that he suffered from a strange illness for several years when he was a child.

"When Han'er was just learning to read, his father taught him to write his own name, and he made a fuss about changing his name."

"His father asked him why, and he said that the character '易' (Yi) is black, the character '水' (Shui) is yellow, and the character '寒' (Han) is dark blue, and it looks too ugly when put together."

"His father thought he was being silly. Aren't all the words written with ink black? Where did the yellowish-brown color come from?"

"Han'er insisted that every word had a color."

“At first I thought he was just joking, but then I found out that he seemed to really think so, so I thought he had hysteria and took him to the temple to have a religious ceremony.”

"After the ritual, it didn't get better, so we found a Taoist priest, but that didn't work either. My husband and I were extremely worried."

"He sees words in colors, which makes reading particularly difficult because some words are too light to see on the paper, while others are a jumble of colors that makes him dizzy..."

"That's why he preferred martial arts to reading and writing when he was young."

"When he was six years old, something happened to him in the palace. He had a high fever for a few days after returning home, and his habit of seeing colors in words disappeared."

"He was melancholy for several days, probably because he felt sad that he had lost his special ability."

Xiao Qingyin was quite surprised to hear this, not expecting that Yi Shuihan had actually suffered from synesthesia when he was a child.

This synesthesia is not a rhetorical device, but rather a form of sensory association, where visual, auditory, tactile, and gustatory senses are automatically linked together.

For example, you can hear music while eating, smell the fragrance of flowers while listening to music, or, like Yi Shuihan, see colors while reading text.

This condition is quite peculiar.

Unfortunately, Yi Shuihan's synesthesia disappeared after a high fever.

Otherwise, the idea that "even the living Yama sees words in color" would create a strong sense of contrast.

Xiao Qingyin told Princess Zhaoyang about her synesthesia.

Princess Zhaoyang suddenly realized: "It's a disease with a name. I thought it was some kind of strange ailment."

As soon as the sound faded, Yi Shuihan's voice rang out from the outer room.

"Mom, is the bee therapy over yet?"

Princess Zhaoyang raised an eyebrow: "Why are you asking this? Do you think I'm taking up your future wife?"
