"Only a great and pure example can guide us to have noble thoughts and behaviors." Indeed, idols are like a mirror, and they can see their own gaps. As long as others have strengths, we should learn with an open mind. The establishment of idols is neither achieved overnight nor once and for all. It needs long-term consideration and continuous cultivation. In short, to establish idols, we must first have a humble attitude. If you are self-aware and often don't satisfy your knowledge and conduct, you can discover the strengths of others, discover your own shortcomings, and sprout a strong desire to learn from others. Second, be brave in change. "People are not sages, to err is human." Shortcomings and mistakes are not terrible, just correct them quickly. Then you need to apply what you have learned. With a good idol, it is necessary to analyze what is good about others and how hard you work to catch up. As soon as I heard the exemplary deeds, my eyes filled with tears and my blood boiled. In the actual work, we still go our own way step by step, which means "learning hard but not being tempted to do it". Such a learning attitude is absolutely not acceptable.
