No.

1. This event is hosted by the Children's Channel of Dongguan Radio and Television Station. It is a stage designed to provide a stage for children in Dongguan to showcase their talents. This means that the organizer of the event is an official institution with credibility, and the official has the responsibility and obligation to provide a safe, fair, and meaningful platform for participants.

2. The main purpose of the Dongguan Radio and Television Children’s Musical Weekend Show is to cultivate children’s interest and love for music and provide them with an opportunity to showcase and learn. The scam is to deceive people for personal gain, and the organizers of this event have no motive for personal gain, but hope to have a positive impact on children through this event. So it's not a scam.
