You can delete the information directly, it is not easy for him to find. As long as he knows your ID number, it is easy to find the room opening record, because the hotel accommodation information is networked. As long as he knows the person at the front desk of the hotel and enters your name and ID number on the computer, he can find out your check-in record.

As long as you haven't checked in in the last three months, the check-in records of the first three months will be automatically deleted. But the opening record left in the public security system is permanently retained!
