Precautions:
For example, a child of 15 years old, if a younger child calls him strange uncle, it must be mentally ill. Or a wretched middle-aged man abducted a little girl to invade.
If accompanied by corresponding outreach, this hint is even stronger. For example, sending lollipops and watching goldfish. For example, "strange uncle who cheats little girls to see goldfish", "strange uncle who likes to do morning exercises" and "strange uncle who only uses soap in the bath" must mean this.
