A challenge here was that many members of this group were not fluent in English, and the question was whether a coherent presentation could be made using a translator, which would mean that I had to condense my material for the allotted time.
Fortunately, a wonderful Mandarin speaker helped immensely. She stopped me every 5 to 10 minutes, and summarized the gist of my comments in 2 or 3 minutes. The audience was attentive, and felt they learned much of value. At the end, a delicious ad nutritious Chinese meal was enjoyed by everyone.
