Yan'er overheard the old man say at a friend's house that 12-year-old children are connected to supernatural beings and can see some chemical phenomena that adults cannot see - supernatural beings. After hearing this, I thought, "Think about it, those of us born in the 1980s who are about to turn 30 must not believe in these so-called supernatural events. The people born in the 1980s were born under the red flag and grew up in the era of scientific knowledge. Haha... So proud!"
