Let parents bring their children's calligraphy works back to the exhibition.

1. Explain the reasons: explain to parents the reasons for taking back the works, such as the need to select and tidy up the exhibition space, so that parents can understand and support this decision.

2. Thank you for your support: Thank parents and children for their support and participation, express their recognition and appreciation of the works and ideas, and remind parents to pay attention to the collection time again so as not to delay the trip.

3, with the help of communication tools: you can use social media or SMS and other communication tools to send information to remind parents, which is more convenient and fast.
