The brushwork in this calligraphy is vigorous and forceful, with a real classical feel.
Tips
usage
Two distinct senses: (1) describing a person — 'aged, weathered, careworn' (more vivid and slightly sadder than plain 老); (2) art criticism — 'forceful, mature' as a compliment for brushwork that looks weathered and seasoned.
memory
苍 originally means 'dark green/grey' (think 苍天 grey sky, 苍发 grey hair). Pair with 老 'old' and you get the colour-tinged image of greying age.
