how can we make the rotation of fan opposite?

It depends on the type of the motor that the fan have .If the fan has single phase
induction motor then it is not possible but if it is a 3 phase motor then it is possible
to change its direction of rotation by just swapping any two wire . If the
motor is DC motor then just by changing its polarity the motor will start rotating in the
opposite direction .
