Desktop Xiu Xiu 2\ also known as Desktop Dancer.
It's like a fish show. If the installation is successful and can be used by table dancers, it will automatically appear on the table to dance after you click it. If the file itself does not support this service, it is useless to click on it. If you click on other commonly used calendars, you should be able to click on them. To sum up, it is a software problem.
