Dear Sir:
　　I am a business man from America, and my name is David Smith. Last month it was the first time that I traveled to Beijing for business, signing a contract with a Chinese food company. Unfortunately I got a bad flu and then had a fever. I was sent to your hospital. Because my temperature was nearly 40 degree centigrade, I was asked to be in hospital. I worried about my business and the delay of signing the contact will lead to great losses to my company. However, After the doctors' careful treatment and nurses' patient care, I was recovered only in 4 days.
　　I completed the negotiation¹ with the food company smoothly² and signed the contract on time finally. So I sincerely appreciate all the staffs in your hospital who helped me full-heatedly. I was deeply impressed by the kind doctors and nurses, the pleasant and comfortable environment, and considerate services. I have no relatives and friends in Beijing, but I felt at home in your hospital. I will always remember all those warmhearted persons and your hospital in my heart.
　　Best wishes to you all!
　　Sincerely yours,
　　David Smith
