The slogan is not well chosen.

The ancients once said, "Winners are not proud and losers are not discouraged." When you succeed, you must never be proud; After setbacks and failures, we must never be discouraged. No matter what we do in life, we should adopt this attitude. Success is temporary, failure is normal, winners should not be superior, and losers should not lose confidence in progress. These attitudes should not exist. We should guard against arrogance and rashness, try to find our own weaknesses and strengthen our practice.

In other words, they are not proud when they win, nor discouraged when they lose.
