How to write Tomb-Sweeping Day's composition in 400 words?

Today, remembering the sages and deeply paying homage to the ancestors, the arrival of Tomb-Sweeping Day may not only bring a drizzle, but also give us a chance to reflect. Day after day, year after year, when the light rain soaked the green lawn and the words on the tombstone were washed more clearly by the rain, have we ever thought about how to enrich our ancestors and live a valuable life? The graves of our ancestors not only reflect the memories of our loved ones, but also reflect the spirit of an era. Our ancestors were hardworking and kind. In the most difficult years, our ancestors survived with their tenacious posture. Our ancestors also taught us knowledge, which made us smarter. They taught us how to make a fire, how to build a shelter from the wind and rain, and ... at this Qingming time, it is also time for us to thank our ancestors for their teachings and knowledge. What can we create at this moment to benefit our future generations? Where the ancestors rest, birds sing softly and the breeze blows, bringing a little coolness. The flowers placed in front of the ancestors' graves also swayed slightly with the gust of wind. Looking at the swaying flowers, it seems that you can see the kind smile of your ancestors. "It rains in the Qingming period, and pedestrians on the road want to break their souls. Excuse me, where is the restaurant? The shepherd boy refers to Xinghua Village. " This poem by Du Mu presents a complete picture of the Qingming Festival. People burn paper money and put flowers, wine and fruit in front of their ancestors. On the originally noisy road, the number of cars running back and forth decreased, and a strong sense of missing lingered. Yes, we really need to calm down and think carefully at this time. What can we do? I think the spirit of our ancestors. We must strive to create success and live up to the expectations and teachings of our ancestors.
