Competition exists objectively. One cannot walk ahead of others all the time. When people fall behind, it is often through thinking, drawing lessons and improving methods that they can achieve further development. Of course, there is not only competition between people, but also cooperation and communication are necessary for life. We should develop friendship in cooperation, learn to communicate in discussions and debates, inspire each other, broaden our vision and broaden our thinking, so as to make common progress. Cooperation and competition are dialectical unity. Cooperation is for better competition.
