From Lu Xun's "Dissatisfaction" in 1919: After all, they defeated militarism, but their critics still blame themselves and have a lot of dissatisfaction. Dissatisfaction is an upward wheel that can carry dissatisfaction. The human race is moving forward towards humanity. There are many races of people who are not complacent. They always move forward and there is always hope. There are many races of people who only know how to blame others but do not know how to reflect. Woe to you! Baidu

About Meaning: People cannot be self-satisfied with some achievements. They must always have strict requirements on themselves and have a desire to improve, so that they can make progress. This "dissatisfaction" does not mean greed, but pride and complacency.
