Are the slogans "Fishing fines" and "You bear the consequences" legally valid? If so, what is the specific process?

————The answer has been modified 3.8 Thank you for the invitation. 1. The problem of "No Fishing" slogans The slogans themselves certainly have no legal effect. Of course, it cannot be judged that the behavior is illegal just for the reason of "there is a sign prohibiting fishing here but you fished". It must be based on the law. However, in fact, many local laws and regulations prohibit fishing in public waters, especially in big cities. The slogan is just a reminder that if you still fish, you will be fined. The basis is not the "legal effect" of the slogan, but the law behind the slogan. Of course, it would be another matter if the slogan was fabricated out of thin air and had no legal basis. Of course, since most people don't read government regulations and local regulations... we'd better listen to the slogans. 2. Is the question about the slogan "at your own risk" referring to the slogans posted in factories such as "Do not approach important construction areas, otherwise you will be responsible for the consequences"? Let me understand it this way. Take the factory as an example. At this time, the situation must be considered. You cannot rely solely on this slogan to avoid liability. In addition to this slogan, we must also examine whether there are other warning measures. Are the warning measures sufficient? If something goes wrong, these will be used to determine whether the factory bears responsibility and what proportion of the responsibility it bears. If the factory only has a sign saying "No approaching at your own risk" and there is no warning line, you will still have to bear greater responsibility if something goes wrong. It can be arbitrarily argued that this slogan is invalid. But it must be very useful and is recommended to be followed. PS. The legal issues are broad and profound. If there are any mistakes, please forgive me and point them out in the comments for encouragement. Thank you!
