Preface: He was born in a police family. His childhood ideal was to become a respectable policeman like his father. But everything changed on his birthday. His father did not return home to cut the cake with him as promised in the evening. The next day, a group of uncles wearing the same uniform as his father came to the house and told his mother and him that his father had died and would never come back. A month later, when he came home from school, he saw his once-laughing uncle talking to his mother with a serious face in the crack of his mother's room. He also learned that his father was a traitor. He reported to the criminal gang and the operation failed. He was also hit by a stray bullet during the operation. It turns out that the death of the father he always admired was not a sacrifice, he was just a traitor. She had no ideals since she was a child. She just wanted to see her father every day and let her father touch her head. She smiled and said, "My daughter is taller again." But her father was very busy, so busy that she didn't even see him for many days. She understood that her father was making money for a better life and to protect many people, so even though she was very reluctant, she would still go home after class to have dinner at Grandma Li's house every day to do her homework, take a bath, dry the clothes in the washing machine... And do these things that she could do well so that her father would not worry. But one day an uncle he had never seen before came to the house and told him that your father will never come back and I will take good care of you. After that, the man who smiled and touched her head was no longer in her life, and her only relative disappeared.
