I want the whole world to know the person I like, what should I do?

Invite the person you like out and organize some people to help you hang up a banner saying "XX I like you" in the square (you can attach a photo of XX). Finally, he took a bouquet of flowers in his left hand and a loudspeaker in his right hand and went to the square and shouted: "xx, I like you." (You can use the loudspeaker to make a super sentimental confession) and then kissed in public. In this way, half the battle is won. In the end, you have to spend a lot of money to hold a press conference to announce your engagement to XX.
