From the gold content of the competition, I offer a train of thought:
First of all, let's see if the competition is an event recognized by the Ministry of Education and how good it is.
If this activity is not on it, you can look at the organizer and see the organizer. The organizer of the event is the National Network Security Base, and the network security major alone has a certain influence. As for the signing opportunity, it is only a propaganda means to attract competitors. Whether to participate or not depends on personal wishes.
