"With copper as a mirror, you can be well dressed; Taking history as a mirror, we can know the rise and fall; Taking people as a mirror, you can know the gains and losses, "said Emperor Taizong. A mirror is a mirror for you to learn, so as to better regulate your behavior. The vast history of the Chinese nation is such a mirror. Looking back, we can always gain a lot. Now people's hearts seem to be more and more fragile. When I met a little setback, I thought I was the most unfortunate person in the world. I sighed when I saw the newspaper report about college students' suicide yesterday. A young life withered before it could bloom. The reason why he committed suicide was that he was given a cold shoulder in a job interview. I can't help sighing that modern people should take a good look in the mirror. The mirror of history will teach us how to face setbacks. He once "walked out with a smile" and shouted "Are we Artemisia selengensis people?" However, the slander of the secular, the intrigue of the officialdom and the indifference of reality cooled his enthusiasm when he fought the sword out of Sichuan. In the face of such setbacks, Shixian threw out "the green fly is easy to see, but the snow is difficult to adjust!" I left with my left hand. I can't do anything in my life, but I was born to be useful. Trouble, an eternal obstacle, is just a cup of turbid wine! Beware of the mirror clouds, the waves are flat, that is, breaking the fog and shining, sailing and sailing. Therefore, Wen Yuan's poetry circles echoed with the poet's vigorous evening songs. At the same time, history also shows us that Xiang Yu, the former overlord of the western Chu Dynasty, magnified his pain and achieved his tragic life when he encountered setbacks. History tells us that life without setbacks is not peerless glory; And the life that can't extricate itself from the pain after setbacks is doomed to be a tragic life. In the face of the alarming increase in suicides, I also found that they have a striking similarity: most of the reasons for suicide are too concerned about other people's evaluation of themselves or some unimportant things. I can't help asking: Why are modern people so short-sighted? History tells me that it is because they only have themselves in their eyes, without higher pursuit and belief support, so they lack thinking and understanding of their own life value. Let the mirror of history show us what we should pursue in life. Zi Chu hesitated and died nine times without regret; Zhang Qian chased camel bells and rode the Tianshan Mountains alone; Wei Qing unfurled flags, and our bows and swords were covered with snow; The woman who built the lake is wyndell dichinson, strong and strong ... History strikes our hearts: people live not only for themselves, but also for others and the motherland. History is a mirror. It says that setbacks are a blessing in life. It says that life should have a higher pursuit. It says that "the body develops skin and is influenced by parents". With the benefits of this mirror, people should never give up their sacred life easily. People have forgotten their existence and lost their lives. Then, let's keep the mirror of history in our hearts and always tell ourselves how to spend our lives without regrets. The mirror is hung high.
