There is a guy who wears a heavy coat and a cap, never smiles, and sits taking notes whenever a male Chinese singles player has a match. The TV cameras go to him for reaction shots. He's on camera at the AE singles semifinal between Lin Dan and Budi Santoso. Is this Li Mao?
Whoever he is, his leather cap and heavy leather coat is a big improvement over the black baseball cap and long purple nylon coat he used to wear :-)
