What should I pay attention to on the day of the Universiade?

You don't need to pay attention to anything. The replacement of solar terms is the change of the position of the earth and the sun. People are too young to feel changes. Unless they are well-trained and extremely sensitive, the Universiade is the migration and change of their own moon columns. This change is widely felt by people. Big things can't happen as soon as you get lucky. Don't be superstitious or neurotic.
