Ink and colors.  Two clumps of wheat, fully mature and pendant, symbolize a bountiful harvest which in Chinese is traditionally called "chia-ho".  A pair of butterflies, a dragonfly and a bee are seen flittering among the leaves, providing the scene with a sense of peace and propitiousness.  The brushwork is assured and fluid, lively and accurate.  The work is unsigned.  The title and authorship are ascribed by the Ching collector Liang Ching-piao.

Wu Ping (12th century) was a native of Wu-chin in Chiang-su Province.  He served in the imperial painting academy as tai-chao during the Shao-hsing era (1131 - 1162), specializing in the painting of flowers and birds and sketches of flowering branches which competed with nature herself in life-likeness.  His work was fine and minute, beautiful in splendour.  His vital dates are not known.
