In the long history of mankind, there have always been those who, like candles, burn themselves to illuminate others. Their selfless dedication and outstanding contributions have become eternal models for us. This spirit can be described by many four-character phrases, such as "exhausting oneself to the utmost," "selfless dedication," and "dedication to the public welfare without considering personal gains or losses," all of which express a spiritual attitude of working selflessly for others or for a certain belief.

First, let's talk about "exhausting oneself to the utmost." This phrase comes from the "Biography of Du Mi" in the "History of the Later Han Dynasty." It originally meant to do one's best and spare no effort. Nowadays, it is often used to describe those who work tirelessly for a career or a belief, even sacrificing their personal health. Such people are not uncommon in our lives. They may be busy doctors, diligent teachers, hardworking farmers, or enthusiastic volunteers. Their efforts are often unnoticed, but their contributions are obvious.

Next is "selfless dedication." Although this phrase does not have a definite source, its meaning is very clear, namely, to provide help and services to others or society without compensation. This spirit can be found in many great figures, such as scientists who diligently research for the advancement of science, often not for personal fame and fortune, but for the welfare of humanity. Similarly, countless philanthropists and volunteers have interpreted what true selfless dedication is with their actions.

Finally, let's look at "dedication to the public welfare without considering personal gains or losses." This phrase comes from the "Zuo Zhuan" and means having a broad mind and no selfish motives. In today's society, this phrase is often used to describe those who can abandon personal interests and consider issues fairly and impartially when handling affairs. Such people are valuable assets in any field, their integrity and fairness bring positive energy to society, and they also set an example for those around them.
