Calligrapher's expressive strokes reveal his mental picture

An exhibition at the National Art Museum of China offers a glimpse of Sang's calligraphy world, showing dozens of works done in various scripts and styles. It runs until May 14.

Born in 1944, Sang has been committed to calligraphy over decades. He was a vice-chairman of the calligraphers' association of Nanjing, Jiangsu province, for years in the 1990s and 2000s.
