This is the prevailing custom here: the eldest brother is like a father. The eldest brother means taking up the family responsibilities, taking care of younger siblings, and bearing more duties.
No wonder An Yiqing thinks this way.
An Jing smiled and patted An Yiqing's head, "Go and see your godmother later. With you defending her like this, she will be very happy to see you."
"Okay!" An Yiqing nodded immediately.
An Jing continued, "If something like this happens again in the future, come back and tell your father and mother. Your father and mother are still young and can handle these matters. Once we're too old to protect you, then you can protect us."
"No!" An Yiqing refused immediately. "I've grown up now; I can protect you all. I don't want you to worry anymore. I want you to enjoy life now."
An Jing was even more gratified. Whether he can achieve it or not, she was happy that her son had this intention.
