Just like a sleepwalker wandering in a drowsy sleep, when he is wandering on the edge of a cliff, if he suddenly wakes up, he may fall off the cliff.So is my Emile.In the innocent dream of ignorance, he escaped from traps he never saw, and if I woke him suddenly, he might stumble and fall.Let's try to keep him away from the cliff's edge first, then wake him up and let him observe from a distance.
