One year, the respected Comrade Kim Jong Un visited a sanatorium. The sanatorium, which had been known as the only sand hot spring in our country for hundreds of years, was frequented by a large number of people for various kinds of therapies such as physical therapy, pelotherapy, etc. Satisfied that the sanatorium had a good reputation across the country and achieved successes in treating patients, the respected Comrade Kim Jong Un went round several treatment rooms one by one with a broad smile on his face. Then, saying he could notice that the doctors and nurses had made great efforts for the treatment of patients while going round the treatment rooms, he stressed the need to make every effort to further enhance curative effect in accordance with the nice buildings and well-furnished treatment rooms. Looking at the officials, who were determined to make strenuous efforts for more successes in treatment, he friendly said that the important thing in enhancing the effectiveness of patient treatment is the sincerity of doctors.
