The structures of them were determined to be 1, 2-dihydro-isoquinoline compounds, and the mechanism of the reaction was proposed.B.

However, classical artists' short venture into the human form's interior was to return once more to the human form's exterior, from that point onwards rendering more accurate and subtle depictions of human facial features and expressions; it is the body's exterior that moves people, that entertains, and is the ultimate goal and objective. The most typical examples are da Vinci's "Mona Lisa" and "Lady with the Ermine". It seems as if the skeleton is the one thing Luo Quanmu demands of the world. He has returned the world to its original state, solidifying it into a structure with a static framework.
