British custom
This question is interesting!

If it is Britain, does it count to ban the slaughter of swans?

Since 12 century, the wild swans on the Thames and its tributaries belong to the royal family, and it is illegal to slaughter any of them. Every year, the British royal family sends someone to count the number of swans. Some foreign students were almost repatriated for trying to slaughter wild swans.

And it's illegal to bring big things home.

In London, according to Article 54 of Scotland Yard Act 1839, it is illegal to roll or move any large objects such as wooden barrels, cylinders, ladders, wooden boards and posters. On the sidewalk (except for carrying such articles up and down from roadside trolleys or carriages), and impose a maximum fine? 500, but this rule only applies to London.

I heard from an overseas student who came back earlier that it is forbidden to sing birthday songs in public. ...

Due to copyright issues, the law stipulates that you can't sing happy birthday songs to your friends in public, otherwise you will have to pay.

I can't think of anything interesting for the time being. Let's talk about everything we think of. I am also very curious to say!
