My friend is underage, but can I stay at home with my ID card?

You can live at home if you have an ID card. Although you are a minor, you have legally obtained your ID card, which shows that you are a legal citizen and can enjoy the corresponding citizen treatment. Moreover, the hotel stipulates that all people staying in the hotel need to show their identity documents, which has met the conditions.

Although you have identification documents, for personal safety, try to stay in the hotel accompanied by family members or relatives.
