About
Hey, I'm XingKaiXin. I work in Shanghai. Outside of work and study, I'm a photography enthusiast who also loves tinkering with all kinds of gadgets.
Life shouldn't be just one kind of experience, and not everyone has to be laser-focused on one thing. Having wide interests and a life full of experiences is its own kind of happiness.

Hey, I'm XingKaiXin. I work in
Welcome to my upside-down world. I write about AI coding and agent engineering, build small, handy tools, and keep notes on life.
Life shouldn't be just one kind of experience, and not everyone has to be laser-focused on one thing. Having wide interests and a life full of experiences is its own kind of happiness.

The pond in the yard
After the credits, come sit in the yard for a while. Seven koi live in the pond.
Tap or drag the water · or pick up the rod and fish
Seven koi swim in the pond. Tap or drag sideways across the water to make ripples. Once you pick up the rod, move the pointer or tap the water to place the float; when a koi bites, tap or move the mouse up to strike. With a keyboard, press Enter to start, the arrow keys to move the float, Enter or Space to strike, and Escape to put the rod down. Every koi you catch goes back into the pond.
