Dear Ms. Green,
Hi, my name is Li Hua, I live in Beijing, zhankuanlu #56. On november 28th, my mother hurt her leg while riding her bicycle.I want to thank you for taking her to the hospital and sending her back home! My mother's leg is a lot better now, without you, I do not know what will happen to my mother! You have saved my mom and I want you to know that I really appreciate the help! My mother and I are going to visit you, we want to thank you in person! What time will you be available? Please reply and thanks again!
