> Turns out this is very intentional, and China uses a different geographic coordinate system than the rest of the world. WGS-84 is the most common coordinate system, but China uses GCJ-02, sometimes called Mars Coordinates. Part of GCJ-02 is an algorithm that obfuscates the results. So applying any GCJ-02 coordinate to a globe using WGS-84 coordinates gets distorted like a funhouse mirror.

A lot of countries use their own coordinate systems, that make their countries look flat on a x/y plane. Eg. my country - slovenia.

Usually those coordinate systems are easy to calculate to wgs84 or web mercator projection[0], compared to the chinese solution
