I think this kind of science and technology innovation competition is still very useful.
Students can practice their hands-on skills by participating in science and technology competitions. It is really a sense of accomplishment to get recognition from others through their own efforts and based on their own ideas! Moreover, science and technology competitions can stimulate everyone's creativity, and innovation can rejuvenate a country.
Students generally participate in various competitions rarely alone, usually in groups. In this way, students' sense of teamwork can be cultivated, their ability to communicate with others can be cultivated, and their ability to communicate with others can be improved during the competition. Maybe you are the original goal of starting and participating in this kind of competition.
A large number of outstanding intellectual talents will emerge in every science and technology innovation competition, and communicating with these outstanding talents can also broaden your horizons.
