Dear Dong Ping,
Sorry
My apologies for the 'delay' to answerin answering you, but I only had a short time given my schedules and some problems (...). VeryI am very happy for your success in your career (!!) and maybeI wish you happiness in your family life and with your friends.

Thank you for your invitation to China, but I have to find some money to go, maybe in June-July (?), Ifif that suits you ?
Friendship.
Warm regards,
Serge
