First, the character is misspelled; it should be 'one day'. Secondly, this thing is neither legal nor illegal in the country. How many times do I have to say this? In short, it is not protected by law, do you understand? The Communist Party does not want you to engage in these things ideologically, but they also do not want to admit that this thing is legal, after all, it is difficult to control, and they don't have that capability. Sheep? Just be obedient, and if you engage in these things, I can't control you, what should I do? It definitely won't be good, understand? Elementary school student.
