Nowadays, there are many kinds of "training" in society, and it can be said that most of them are out-and-out liars. They have beautiful and charming names, as if they could become Einstein and Bill Gates through their "education". Actually, it's all nonsense.
If you want to participate in the current "training" at your own expense, you must weigh and inspect it repeatedly in advance, listen to the opinions of those who have participated, don't pay in a hurry, and leave immediately if you can't see it. It's hard to wait until the tuition is paid to them and you can't receive the corresponding training and reason with them. They have good mouths, which will make you speechless. It's no use reporting them to the relevant departments.
Therefore, in the face of social training, we must be extra careful!
