Can a foreigner stay in a hotel with a green code marked with an asterisk?

Yes, you can. According to the local epidemic prevention policy, you need to produce a negative nucleic acid test certificate within 48 hours. You can check in after signing the letter of commitment, but you are encouraged to take the initiative to conduct nucleic acid testing. During the stay, the hotel staff will check the color of the "health code" every day to ensure sustainable accommodation.
