How does yy Medal Hall light up Virgo?

It's actually quite simple. Look at the personal information, then look at the medal of achievement, click a constellation medal at random, then enter the search channel in the sign-in mode, enter the channel number to sign in in the upper right corner, click the magnifying glass, and then four Chinese characters will appear at the top right in the middle. I want to log in and click on it. The check-in position of each channel is either in the lower left corner or in the lower right corner.
