Why is Jingdezhen called the porcelain capital?

Jingdezhen has always been famous for its porcelain. In the Ming dynasty, the famous Gothenburg sailed for the Netherlands, carrying a large number of porcelain produced in Jingdezhen. Jingdezhen porcelain is exquisite and elegant, known as "white as jade, bright as a mirror, thin as paper, and loud as a chime", which is widely praised at home and abroad. Ancient foreigners called china China (meaning porcelain). Now China's English name is China, so Jingdezhen is directly called the porcelain capital, and the people in Jingdezhen have also become the porcelain capital.
