Mr. Green, it is a notice to the audience. It says that we should enter the concert hall 30 minutes
earlier before the concert starts. Entrance to the hall is by ticket only, each one each ticket. As a rule,
food or drink should not be taken into the hall .Of course, smoking is not allowed in the hall either.
Please don't bring your digital cameras with you because no photos can be taken during the concert.
And what is more, mobile phones must be kept off during the concert.
