The intelligent early education machine can't play pinyin ancient poems, which may be related to the files stored in the memory card. You can try the following methods:

1, check whether the capacity of the memory card is enough, and ensure that the files in the memory card are not damaged or deleted.

2. Confirm whether the format of the memory card is correct, for example, whether it is in FAT32 format.

3. Check whether the memory card is inserted correctly. Please insert the memory card after turning it off, and then try to turn it on again. If the above methods can't solve the problem, it may be necessary to further check the setting of the early education machine or the hardware itself. I suggest you contact after-sales for help, or consult the customer service of the manufacturer.
