This, however, is more easily said than done; for Dr. Hü's sympathetic heart makes it very hard for her to spare herself as long as any one needs her help. For nine years after taking charge of the Woolston Memorial Hospital she worked almost unceasingly, with practically no vacations except those caused by the necessity of closing the hospital in the summer, and these she made as brief as possible. But during all this time the work had been steadily increasing, until finally, in 1907, when the number who thronged the hospital and dispensary was greater than ever before, the doctor's health broke down under the strain, and, although with the greatest reluctance, she was forced to stop work. Her fellow-missionaries insisted that she leave the city during the terrific heat of summer, and go to Sharp Peak for some rest. She had been there only two days when she was taken dangerously ill, and for weeks and months the gravest anxiety was felt concerning her. But she received the best of care and nursing, and finally, in March of the following year, she began gradually to recover. Some advised that the hospital be closed. But Dr. Hü's younger sister, Hü Seuk Eng, who had received her medical training in the Woolston Memorial Hospital under Dr. Hü King Eng, and had been associated with her sister in the hospital work for some years, said that to close the hospital would be a great shock to Dr. Hü, and a bitter disappointment to the people, and that she would undertake to keep it open. "The load was indeed very heavy and my heart was truly frightened," she admitted afterward. "Every day I just repeated that comforting verse, 'He leadeth me,' and marched forward." At first the people did not have the confidence in Hü Seuk Eng which they had in Dr. Hü King Eng. Hü Seuk Eng tells of their great eagerness to see her sister: "The faith of many of the patients has been so strong that they thought their illness would at once be cured, or at least lessened, if they could only touch Dr. Hü's garment or hear her voice, or merely look into her face. During these months of sickness many people came wishing to see 'the great Dr. Hü.' They did not want to see me, whom they termed 'the little Dr. Hü.' Some of the leading gentry pleaded with the hospital servants to present their cards to Dr. Hü, and she would be sure to come out to see their sick friends. For it is fully nine years since she was appointed to take charge of this city work, and never once has she been so ill. Indeed, it is the first time she has not been able to respond to pressing calls for medical treatment. So often were heard the words, 'I want the doctor whose hair is dressed on the top of her head and who has graduated from an American college,' that my fellow workers advised the same coiffure in order to avoid trouble; but I told them when the question was asked again just to answer, 'This is Dr. Hü's younger sister, and she will do the best she can.'"
