1. System failure: The input information system used by the kindergarten is out of order, resulting in the information not being input or transmitted normally.
2. Human error: Parents make mistakes when filling in information, such as filling in the wrong contact information or missing required items.
3. Network problem: In the process of information entry, the network connection is unstable or interrupted, which leads to the failure to transmit information to the kindergarten in time. Kindergarten is an educational institution that provides preschool education and care for children aged 3 to 6. This is the children's first educational experience before they officially go to primary school.
