in the evening, my parents and I came to the northwest people's house and entered the room. At first glance, we saw my grandfather sitting in a chair. My mother and I put the cake on the table and sat down. Soon, Brother Shuo Shuo and others came, and everyone was here. My uncle put on his birthday hat, and grandpa was very happy. We put the cake on the table, so I noticed. I asked my mother. My mother smiled and took out a small box with music candles written on it. I opened it. Isn't it a plastic flower? How can you be a candle! I gave the flowers to my mother with questions. Mother put plastic flowers on the cake, and my brother picked up a stick of incense after turning off the light. After lighting it, he aimed the burning incense at the red dot in the center and pressed it. Suddenly, a flame came out from the middle, and then the closed petals slowly unfolded. There was a small candle on each petal. It was amazing, and there was music. We also sang a birthday song to grandpa with the music, and grandpa closed his eyes and made a wish. Several of our children also stood up and wished Grandpa a happy birthday. Looking at Grandpa's happy smiling face, let alone how happy we were!
