On the eve of the college entrance examination, my head teacher Zhou Mingyuan sent me a message. When you enter the examination room tomorrow, don't write your name first, look at the invigilator's left hand first. I stared at the screen three times. Just as I was about to type and ask him what he meant, the message was withdrawn. Then came another one: don't write your name. Then - he blocked me. I was sitting on the bed in the rental house, holding the old mobile phone with only 23% battery remaining, and my mind was filled with questions. The ending is sweet and has no bad direction.
