I am in Beijing New Oriental Youneng Middle School, and I feel similar to you. I'm very tired. Is there any practical value? In short, I feel like a sweatshop. I'm not saying that New Oriental is service-oriented. Why do I feel that teaching assistants are not treated like people? Working outside every day is very busy, and I have to listen to instructions. It doesn't feel human at all. I don't know what this posture is suitable for exercise. Really energetic college students can do some practical and useful work. I think if xxx is allowed to do it for a day, he can't stand it. High intensity, many of which are useless, is a realistic place.
