After releasing “Ancient Chinese Paintings from the National Palace Museum Postage Stamps — 24 Solar Terms (Autumn)” on August 3, 2022, Chunghwa Post has followed up with a series 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 second set contains six stamps, each valued at NT$ 12, depicting winter with its six solar terms: Beginning of Winter, Light Snow, Heavy Snow, Winter Solstice, Lesser Cold, and Greater Cold. 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.
