Don't be clear about your old friends, remember the truth in your daily life and fitness, and give up the dust of Chang 'an for those who are so grateful to you. Does anyone know what this means? Explain it in detail. ... Hello. The first sentence "suppress" should be changed to "don't". This poem is generally used for examinations, fortune telling or divination. You, don't tell others, especially friends, live a regular life and pay attention to physical exercise. One day, I may be heartbroken for the love in the middle. Without my previous happiness, I will bear hardships and burdens. Don't tell people right and wrong, go to bed early and get up early to exercise, don't fall into the world of mortals and stay away from secular disputes. After the answer, I wish you good health and all the best. Please adopt it. Thank you.
