coordinate transformation

I got confused over time of coordinate transformation for a point in space v.s. transformation of a point location with fixed coordinates. It turns out that the former is the exact reverse of the latter. I don’t include a proof here, but it should be self-evident.

Also it is much easier to understand coordinate transformation with the bra-ket notation in physics. Hopefully, my sketch below is clear enough.
