Dear Mr. Takashhi,
I am writing to apologize for any misunderstandings that occurred when I showed you around Beijing the other day. I noticed that you were a bit 31 when I put the business card you gave me in my 32 without looking at it. And 33 did not know why you kept making an OK sign and why you 34 so many things. After reading a magazine article, I know that Japanese people give out their business cards 35 they greet others and they would like others to look at their cards carefully. So I should have read your 36 before I put it in my pocket. And I also know why you bought so many things 37 . Because gift-giving is expected in Japan and on a trip, you must bring back lots of 38 . As for the OK sign, I now know it is a request for small change.
I feel very sorry for not having known these 39 habits earlier. I hope you can forgive me for all these misunderstandings. I hope 40 our next meeting will be happier.
Yours sincerely,
Li Hualing
