The image shows a blackboard with text written in Vietnamese. The text is divided into two sections, each containing a different message. The first section has the following text:

"Để tài: Sản phẩm chéo tòi vặt tiêu phế Thái thành do dùng day học cho truong móm non."

The second section has:

"Để tài: Sản phẩm chéo tòi vặt tiêu phế Thái thành do dùng day học cho truong móm non."

Both sections appear to be related to educational products and their usage in schools. The first section mentions "day học cho truong móm non," which translates to "day school for kindergarten students." The second section seems to be discussing the same product or concept but with a slightly different emphasis or context.
