Originally, during Kangxi's reign in the Qing dynasty (1684-1722), Changhua fell under the jurisdiction of Jhuluo County. Thanks to its abundant resources and cultural development, it became a county of its own and was granted the name Changhua by emperor Yongzheng in the first year of his reign (1723). That marked the beginning of Changhua's glorious three-century history. This year, 2023, coincides with the 300th anniversary of the county's establishment. Consequently, Chunghwa Post has specially released a set of two stamps to commemorate the occasion. Descriptions of the stamps follow:
1.NT$8 stamp: The stamp features a map of Changhua dating from Qianlong's reign in the Qing dynasty combined with a historical photograph of Changhua's East Gate (Gate of Farming). The design aims to evoke a sense of nostalgia and reflect Changhua's historical charms.
2.NT$15 stamp: The stamp features prominent Changhua landmarks, including the Confucius Temple, the Big Buddha of Bagua Mountain, and the modern high-speed rail station. This design showcases the journey of Changhua's transformation through time and its pursuit of sustainable development, as it looks forward to the next three centuries.
