There are dates in my grandfather's composition.

This is my grandfather, a thrifty, lovely and kind old man. Do you like it? My grandfather is 76 years old. Grandpa has only a few white and thin hairs on his head, and usually wears a small taupe felt hat. Due to the passage of time, grandpa's bags under his eyes slowly fell down, and years carved deep wrinkles on his bronze face like running water. My grandfather is knowledgeable because he is eager to learn. Study even if you are ill. He always touches the book in his hand, just like a brave soldier can't leave the gun. As the saying goes, "It's never too old to learn." My grandfather is such a person. I remember once, after my grandfather finished lunch, he was absorbed in reading in the world, while I was playing happily with my friends. After a long time, I came home, and this scene caught my eye: Grandpa was reading a book like wood, and I couldn't help asking him out of curiosity, "Grandpa, what book is this?" It's beautiful! Show me? " But grandpa didn't hear it, like cotton in his ear. "Hey, grandpa's ears are very similar at ordinary times! What's the matter now? " I muttered to myself. I said it out loud again. Grandpa just came to his senses and said, "Good! This book is quite good, you can read it. I took this book, the title of which is Zhuangzi. I read a content. " I am bored to death. "I turned and walked out again, thinking: I really don't understand that grandpa likes reading this kind of book. Grandpa is not only eager to learn, but also often helps me with my studies. On one occasion, I thought my grandfather seriously proposed: help me with my Olympic math. "Very good! Grandpa promised to come down. From then on, every night, grandpa patiently helped me explain the topic. Grandpa is old, but he has a clear head and a clear head. I understood at once. Moreover, grandpa will help me with my math, whether it is severe winter or hot summer. This is my grandfather, the person I admire most!
