To present the beauty of ancient Chinese paintings, Chunghwa Post has planned a series of four sets of stamps drawn from the Ink Marvels from a Forest of Pearls (Ⅳ) by Zhang Ruoai of the Qing dynasty, a work held in the National Palace Museum. The first set contains six stamps, each valued at NT$ 8, depicting autumn with its six solar terms: Beginning of Autumn, End of Heat, White Dew, Autumnal Equinox, Cold Dew, and First Frost. The six stamps are in a se-tenant block and the shaped perforations are at the center of the long sides of the stamps.The Ink Marvels from a Forest of Pearls is a collection of large paintings gathered into twelve albums in the time of the Qianlong Emperor. The albums are named after the Twelve Terrestrial Branches, the fourth album being entrusted to Zhang Ruoai, who painted the 24 solar terms and expressed each term by landscape painting. The paintings use the styles of the ancient masters to express the climate, show customary activities and the state of the natural world, and depict the variations proper to the given term.
