Grandpa's Protection: "The Last Cup of Chongyang Wine"

"Chongyang Wine" "Grandpa, it's Chongyang Festival today. Everyone's going to climb heights and admire chrysanthemums. Since your legs are inconvenient, why don't you stay home and watch TV with me?" I placed chrysanthemum cake and Chongyang wine in front of my 80-year-old grandpa. He took a sip of the wine and smiled kindly, "Climbing heights can ward off disaster. If you young people are happy, then I am happy." I chatted with him, and the living room was filled with the aroma of chrysanthemum wine and laughter. Just then, an urgent news flash came on TV: "Today, on Chongyang Festival, a severe landslide and rockfall occurred on a suburban trail. Rescue teams have been dispatched to the scene..." I was startled and quickly turned my head, "Grandpa! It's a good thing you didn't go, there was a landslide outside..." Before I could finish, I froze. The sofa was empty, with only half a bowl of steaming chrysanthemum wine and a bitten piece of Chongyang cake remaining. My phone rang urgently. It was my father's choked voice, "Son! We just met an old man at the foot of the mountain who looked exactly like your grandpa. He kept saying his leg hurt and he needed to buy medicine, which made us avoid the landslide! When we finished buying the medicine, the old man had disappeared..." My eyes welled up as I looked at Grandpa's kind, smiling portrait on the wall. The Chongyang wine on the table seemed to ripple slightly, as if he had just gently set down his cup and quietly departed.
