or tang

Any of about 75 species (family Acanthuridae) of thin, deep-bodied, tropical marine fishes that are small-scaled, with a single dorsal fin and one or more distinctive, sharp spines on either side of the tail base. The spines resemble a surgeon's scalpel and may be either fixed or hinged at the rear so that they can be opened outward and directed forward. Surgeonfishes are mostly algae eaters and usually do not exceed 20 in. (50 cm) long. The yellow surgeon, or yellow tang (Zebrasoma flavescens), is an Indo-Pacific species, and the blue tang (Acanthurus coeruleus) is found in the Atlantic and Caribbean.

or Li T'ang

(born circa 1050—died circa 1130) Chinese painter. He earned the highest rank in the academy of painting of Emperor Huizong, and after the North fell to the Mongols he went to the South and entered the academy of Emperor Song Gaozong. His landscapes serve as a vital link between the earlier, and essentially Northern, variety of monumental landscape, and the more lyrical Southern style of the Ma-Xia school (based on the work of Ma Yuan and Xia Gui). Li perfected the brushstroke texture known as the “ax stroke,” which gives a tactile sense to painted rocks and suggests the precise and comprehensive reality that Southern Song artists sought to give their landscapes.
