How to post the slogan of washing machine in dormitory?

There is only one way to meet such a roommate. Attach a label (A4 size) to the top of the washing machine. Rules for the use of washing machines: Everyone has the obligation to pay for washing machines. Non-joint purchasers use the washing machine after each payment of 10 yuan, which shall be signed by the joint purchaser in front.

Often deliberately invite people outside the dormitory to visit our room and secretly let others comment loudly.

Please invite leaders or teachers to the dormitory to comment on the benefits of the joint-stock system.
