You just follow the so-called teachers and call for mice.

You will know in a few days that the teachers have already run away at a high point, while you who keep calling and buying, keep silent when you call, and keep silent when you buy. Finally, you cry and ask the teachers if it can still rise? The teachers reply you that the situation has changed and it is indeed not optimistic. You should hold on to see if there is a rebound. If there is, sell it. You answer: Thank you, teacher. #rats
