Over 60 artifacts excavated from the site of the Porcelain Tower in Nanjing, capital of east China's Jiangsu province, are now on display at the Porcelain Tower Heritage Museum. This marks the museum's first update to its exhibits since its inauguration in 2015. The Porcelain Tower, also known as "Bao'en Temple," which means "Temple of Gratitude," was ranked one of the Seven Wonders of the World during medieval times.
