Legend: One day in the operating theatre my supervising surgeon told me a story about a trip he made to China which gave a fascinating insight into Chinese thinking.
He was at a conference giving lectures and hands on instruction in the use of a new design of retractor used for certain operations. The design was rather innovative, and he joked with the local Chinese doctors "Now don't go copying this..."
One of the doctors replied, as deadpan as he possibly could:
"Oh no! We don't copy. Copying is illegal. We improve."
Alternatively, during the Sino-Japanese war the Chinese were attacking a Japanese position on a hilltop. Casualties were heavy and a Chinese Lieutenant ran back to his commanding officer and reported, "General, General, we are losing 20 men for every Japanese"! The General replied, "Good - soon there will be no more Japanese".
Generally speaking, you aren't learning much if your lips are moving.
