Dear Sam,

I'm planning to visit Frankfort during my business trip. I will arrive on 15th February and stay there for about one week. At the exhibition in Shanghai, you had expected that I can pay a visit to your company, so I hope that we can meet each other during this period.

I'll be available on 17th and 18th. Which day is convenient for you? If neither is OK, please suggest an alternative date in the reply.

I'm looking forward to your early reply. Thank you.

Best regards,

Rita Hu
