Who knows the famous story about Tomb-Sweeping Day? (Be as brief as possible)

Mourning day, drizzle like tears; Pedestrians on the road want to die. Excuse me, where is the restaurant? The shepherd boy pointed to Xinghua Village. Just like the famous poem by Du Mu, a great poet in Tang Dynasty, it is drizzling in Tomb-Sweeping Day every year, which always gives people a sad feeling.

No, the annual Tomb-Sweeping Day comes in a drizzle.

This morning, it was another rich day. Wandering around for a while, I feel particularly sad, but it's still inappropriate! I was dragged by my father to have breakfast, picked up fragrant paper and carried a hoe to sweep the grave.

Stepping on the thorns on the road and along the muddy path, we came to the graves of grandparents. After my father cleared the weeds around the grave, I put yellow paper on it, inserted incense and left.

Many relatives have been to the grave, and we braved the light rain to go to the grave for our grandparents. Along the way, flowers and plants, I have no intention to appreciate; Birds singing and insects singing, I didn't mind listening, just came to the grave early. After a while, we arrived. Looking at the lonely grave, I can't help feeling sad. After dad mowed the grass and pasted the paper, we took out the paper money, knelt in front of the grave and scattered all the paper money on the grave. ...

It's raining harder and harder, flowers and plants are interlaced, and the surrounding area is lifeless. This situation makes me feel yearning: I can't help crying when I think of their love and joy before I die and their will before I die. At this time, my father also shed tears. The rain didn't subside, and we cried until we stood up after a long time.

At this moment, I saw the red azaleas in the distance. According to my mother, azaleas, also known as Qingming flowers, bloom in Qingming period, because they are the best things to commemorate and appease the dead. So, I ran to pick a few bunches and put them in front of my grandparents' graves, hoping that they would all be comforted. ...

There is clarity every year, and there is sorrow every year. This kind of sadness can't be felt by anyone. I long for the sadness in the rain, so I long for the arrival of Tomb-Sweeping Day!
