Write a preface of 100 for the maternal love photography exhibition.

The most sacred thing in the world is maternal love. The most precious thing in the world is maternal love. Mom, I love you forever.

How many hot summers, you shook your fan to accompany me to sleep, so that I was no longer hot; How many cold days, you knitted a sweater for me overnight, so that I was no longer cold; In the heavy rain, you braved the fish to bring me an umbrella, which made me no longer anxious; Under the lamp, you analyzed the problem for me, which made me no longer worry. I can't forget my mistake, I dare not face your accusation, and I regret it very much; I can't forget that when I cried, I threw myself into your arms and felt extremely happy; I can't forget it. When I was injured, I was very warm when I listened to your comfort.
