An old man mentioned by the store owner in a conversation about Chen Jin’s father. The store owner says, “Your father was just like you back then, always causing me trouble. But that old man… was just robbing Chen Fangguo of his prime.” The exact identity of this old man is unclear—he could be a competitor, or perhaps the store owner’s own father. He is referred to as someone who deprived Chen Fangguo of his best years, implying a past conflict in the fire‑fighting equipment business.
