Ruqing should have been named Sun after her father, but the name on her household registration was Li Ruqing (the same surname as her mother). One of the reasons that I have to say is that she has a rebellious father, but her son chose not to follow the ordinary path, skipping school, running away from home, escaping from marriage, and giving birth to a daughter out of wedlock. In the end, in order to anger the old man in the family, even the old man's most precious granddaughter deceived her into taking her mother's surname instead of Sun's. And after Sun's father happily lived for a period of time with a daughter at his knees and a beautiful wife by his side. His baby Ruqing finally, with his tearless expression, resolutely embarked on his old path, skipping school, running away from home, being independent and lawless.
