The hot water booster pump in the work hotel is reverse, but aren't the motors all rotating forward? What happened?

The motors are not all rotating forward, that is to say, clockwise! But it does not rule out inversion, that is, counterclockwise rotation! This situation is mostly caused by maintenance or artificial wiring. This situation can be corrected by adjusting the phase sequence of power supply incoming lines.
