April 6

Dear Doctor Zhao:
　I am 62 years old, a retired worker from Shanghai. Since October of last year, I have found my right ear with cicada chirping when I was sleeping in the night, but I didn't think much about this. With the time passing, the symptoms of ear ringing were more distinct. I went to see the doctor in department of eye, ear, nose and throat and was told that it was possibly nervous tinnitus. The doctor gave some medicine named Mi'erbao and vitamin but after 60 days there wasn't any effect.
　Also my mother who is 80 years old has got ear ringing and deafness for many years. We have seen many doctors and taken a lot of medicine but made no progress. My mother is always in bad mood and has no energy because of ear ringing.
　I heard from a friend about your unique way and medicine (Jing Nao Qing Yin series) on curing deafmutism, ear ringing, and headache on 6th April. With great trust I bought the medicine for one course of treatment. On the 6th day of taking this medicine, my ear ringing stopped, and other discomfort also was eased. After the first course of treatment, I was fully recovered. In order to consolidate the effect, I want to go on for a period. I have sent the money, if you receive please send the medicine for two courses. Also I want to ask whether the medicine can be taken discontinuously. If ok, whether there is other matters needing attention. I am waiting for your guidance.
　I cannot come personally due to the long distance from your hospital. Thank you very much for your help.

Sincerely yours,

Liu Yuanqing
