TAIPEI 2023 – 39th Asian International Stamp Exhibition is held on August 11-15, 2023, at Taipei World Trade Center Exhibition Hall 1. To mark the event, Chunghwa Post has released a set of postage label featuring the purple crow butterfly (Euploea spp.). On the lower left corner of each label is a serial number with three English letters (which signify the roll number) and four Arabic numerals. The total is 900 rolls with 1,000 labels each. The purple crow butterfly (Euploea spp.) is a medium-sized butterfly with a wingspan of 4 to 8 cm. When open its fore-wings gleam with a bluish sheen, the stuff of dreams. It breeds throughout Taiwan in spring and summer but in winter it migrates south to what is called overwintering site. In recent years measures taken on the national highway to ensure the butterfly’s safe migration have created a precedent for ecological protection at home and abroad.The postage label will be available on August 11, 2023 in postage label vending machines at the following branches: Keelung Aisan Rd., Taipei Railway Station, Taipei Daan, Neihu, Neihu Bihu, Nangang, Xindian, Sanchong Zhongshan Rd., Tamsui, Tamkang University, Xinzhuang, Fu Jen Catholic University, Linkou, Taoyuan Chenggong Rd., Zhongli Neili, Longtan, Yangmei, Hsinchu Wuchang St., Hsinchu Science Park, Zhudong, Miaoli Zhongmiao, Taichung Minqyuan Rd., Lugang, Yuanlin, Douliou Xiping Rd., Chiayi Yushan, Xinxing, Zuoying, Kaohsiung Railway Station Front, Kaohsiung Xijia, Gangshan, Pingtung Minsheng Rd., Yilan Zhongshan Rd., Hualien Guoan, Taitung Datong Rd. and Postal Museum.
