The power of example "The power of example is infinite", which is an old saying we often say. And our ancestors have long put forward such a wise saying that "taking people as a mirror can understand gains and losses". Hua Yiwei, who was moved by one of the top ten figures in China, chose Bethune as his role model from the day he became a doctor and encouraged himself to be a good doctor like Bethune, which was a "mirror hanging high" in his mind. And an example like Lei Feng, unconsciously moved from ancient China to West Point in the United States. It can be said that any progressive nation in the world will not ignore the power of example. Someone once said, "Sow an idea to reap an action, sow an action to reap a habit, sow a habit to reap a character, sow a character to reap a destiny". Spreading an example, we can always see the goal and reference of struggle. An example is the upward force, a mirror and a flag. It is conceivable that if everyone learns from Lei Feng, our society will have inexhaustible spiritual wealth, the relationship between people will be more harmonious, and the social environment in which people live will be more harmonious. If everyone learns from Bill Gates, it will certainly produce more inventions, bring more material wealth to society and promote the overall development level of human society. An example is like the coordinates of life and the guide to success. It brings us endless spirit and vitality, the belief that we will win, and an endless source of strength. Let's learn from the example and keep up with it, and we will be invincible!
