There are more than 60 million people on the earth, and China accounts for more than 20% of them. There are also many unregistered households and children, and Shandong Province is the most populous province in the country. And I was born in a large family with three grandfathers, three uncles and one aunt on my father's generation, and five sisters in my generation. My surroundings are so crowded and noisy. I want to find peace, but I can't escape the abyss of loneliness.
