the trip was great getting together with you two once again.don't forget the invitation to pop in on me the next time you're in Beijing.
thanks again..and say hello to your sister.
All my best,

Dear Lucy,
I am writing to express my sincere thanks for your beautiful flowers. I’d like you to know how much your flowers meant to me. You have a positive genius for selecting the right gift. I not only enjoyed your flowers, but also the delicate vase. I shall ever remember this gift as one of the most precious things in my life.
I will not be very busy the following days. I hope to have the opportunity of reciprocating. Would you kindly let me know what time you are at convenience?
I will feel very happy if you have time to make me a call. How nice it would be to see you again and I am looking forward to seeing you next time!
I repeat my thanks again for your lovely flowers. Please give my kind regards to your family.
Yours truly,
xxx
