Hello, my name is Yan, and I am a villager in a big mountain village, my hometown. More than 8,000 families have strict surnames, and many villages have them! They all moved out of Gu Yan village! The names of generations are in descending order: 1. Now there is no one in the older generation; 2. Most of them are elderly people; 3. Well, middle-aged and elderly people; 4. Scholars; 5. same as above; 6.c. Youth and adolescents; 7. There is only the Pei family in the village. Note: Although I am only seventeen years old, I am a scholar of our generation. In our village, some old people and middle-aged teenagers call me Uncle Da Die, and even call me Grandpa! There used to be a book called Family History in our village, and I don't know where it went.
