Adventures in Xingxing's Cat Pet Shop

"The Adventures of Star's Cat Pet Shop" My name is Xingxing, and I am an ordinary person who likes donuts, mathematics, and random thoughts. One day, I took my special pet, a little guy who could memorize mathematical formulas, talk about philosophy, and look at me eagerly while I was eating donuts, to the largest cat pet store in the city, and recorded the adventures of the stars when they came to the cat pet store.
