Is there any violation of discipline in taking photos with Lion Kirin in the Forbidden City? My friend doesn't know. You'd better not take photos with this beast in the future.

No violation of discipline. The law doesn't say that you can't take photos with the Forbidden City.

But according to our custom in China, it is best not to take a group photo, because similar beasts are similar to those in the town tomb (actually not the same kind of beasts), and the custom in China is taboo to this, so that even this kind of thing is taboo. Just like Tang Sancai is buried in the tomb, so it can't be put in the bedroom.
