Eggshell painting is common, yet "she created something with poetic beauty", Douban user Freja said.

Born in Jiangsu province, Yu started painting when she was in elementary school. The illustrator officially started to study art in high school.

Inspired by the poetic names and customs of the 24 solar terms, the artist captured the colors and most representative things for each term on her eggshells.
