Warmly remind the mall to upgrade its decoration slogan.

Dear customers (or Taobao style: "dear friends"):

For the safety of your children, please take good care of them and don't let them play on the escalator! Otherwise, it may hurt the child! We all sincerely hope that the child will be safe!

For everyone's shopping convenience. Please don't push the trolley to the first floor after shopping! Thank you for your support!

Because of your support, we have a harmonious and happy shopping mood! We thank you again for your support!

I sincerely wish your family happiness and all the best!

==============================

The above two items can be written separately or combined. There is only one center, that is, between the lines, to make customers feel cordial!
