When is the date of sending the pennant to the ICU doctor?

Either write the date when the patient is discharged from the hospital, or write the date when he expects to send the banner. Because you want to express your gratitude for the doctor's medical skills, writing the date of the hospital does not mean that the doctor has a good medical skill and has recovered from the hospital. This can best reflect the contribution of doctors. But you don't have to worry too much about time. It's almost time for you to leave the hospital. After all, no one went back to study this date in detail except patients and doctors.
