Staying with English family in Suffolk 9

1/Jan Sun (Staying with English family in Suffolk 9)
Today, we went to the real tennis court. “Real tennis” is different from “tennis”.
Rackets and balls and courts are different from those of “tennis”. Rackets have smaller faces and balls are solid with cork and courts are in a house.
I could not understand the rule regardless some explanation, so for me, it looked like that just peoples were hitting a ball.
