The "Perfect Future Star" competition is divided into preliminary and semi-final. Are there two entries? Can a person only contribute one work?

The works of the preliminary contest and the semi-final contest can be different works or modified versions of the same work. The screening standard of the preliminary competition is to see how the artistic foundation of the players is. After entering the semi-finals, the contestants will have the opportunity to study and communicate with the elites on the spot and online for about 20 days. In the meantime, everyone can use it to modify the previously submitted works. Of course, if you are not satisfied with the previous works, you can also re-create.
