I have never been to Song Cheng, and I know there is an invisible house in it. The photos taken are very interesting. Excuse me, people who have been there: how did the photo come out?

A table with legs connected to the mirror, hiding behind the mirror and stuffing your head into a hole in the table. But after all, it is a tourist attraction, which is generally not photographed. If you are really shot, your leg has "disappeared" and your head is still there. If there are interesting places in Song Cheng, I suggest you watch folk tricks on the street or on the stage. Upside down.
