If the player screams when he/she hits the shuttlecock like the tennis players is it legally? in the doubles team, if you stand on the right and serve to the left side of the court. the other opponent on the right hits the shuttlecock, does it count for rally foul?
Screaming is up to the judgement of the umpire. Normally it is allowed. Only the receiver may return the service. If his partner takes it, that is a fault.
