Do I use this couplet for infringement? The people who raise black land on black land are real, and the northeast people are authentic northeast vegetable fields!

It is admirable that you can think of intellectual property protection when running a restaurant.

As written works, couplets certainly have intellectual property rights, which is beyond doubt.

If you want to use it, you must get the authorization of the right holder.

However, in reality, it is unlikely that such couplets will have "intellectual property disputes" and be resolved through judicial channels. Unless your hotel is Shangri-La, Hilton or something.

In practice, I really don't need to think so much about opening a restaurant, although I shouldn't say such things as a legal professional.

If you feel guilty, you can call the obligee.
