The bits and pieces of history are like sand shells scattered on the vast beach. We passed by quietly, greedily looked at these glittering and precious treasures, and sometimes picked up one or two shells that touched our hearts and collected them with love and gratitude as a souvenir.

There is a shell on the beach that has experienced vicissitudes, which is the story of the Jewish nation. When forced to be displaced and homeless in World War II, Jews still held the hope of revival. They never give up and never compromise. They stick to their faith and pass on their courage, because they have a faith-from wailing wall. Wailing wall, which has experienced historical vicissitudes, records the sufferings and past, glory and dreams of the nation. Every Jew will come to wailing wall at some point to commemorate his predecessors. It is this commemorative mood that keeps this nation confident and tenacious, and makes them stand high on the horizon again.

There is a shining shell on the beach, which is Madame Curie's nostalgia for the nation. Madame Curie was poor all her life and left the motherland when she was young. After years of unremitting pursuit in the field of science, she finally extracted the radioactive element polonium from the metal. She knew that this element would bring her countless honors, and she, the grateful scientist, immediately thought of naming this element with "Po" to commemorate her motherland Poland. Perhaps it was this moment that kept Madame Curie working tirelessly. Later, she refined radium and became one of the few women who won the Nobel Prize twice.

There is a grateful shell on the beach, which is the "grass" in the heart of writer San Mao. Sanmao was once confused and helpless when she was studying in a different place. At this time, a strange classmate gave her an ordinary grass to encourage her to refuel. San Mao was very moved. She wrote in "Someone gave me a grass": "The grass will wither, and I don't know how to commemorate this classmate who has disappeared. I can only pass on this helping heart and this grateful heart to help more people. " Sanmao did it with practical actions. She touched and moistened the readers' hearts with delicate words and sincere feelings. This is her way of commemorating.

Some people collect different samples from various sections of the Yellow River to commemorate their ancestors who created splendid China culture. Some people are wandering outside, still carrying dirt with them to commemorate their motherland; And we, in Tomb-Sweeping Day, will always remember those martyrs who gave their lives for our happiness with our thoughts. With a sense of gratitude and a belief, I picked up a few shells on the beach, treasured them in my body, remembered the history, and made preparations for creating the future in my heart.
