As one of the places where silk culture originated, Huzhou city in China's Zhejiang province has a long history of silk production. The city's Qianshanyang archeological site is called the "source of silk textiles in the world" since some fabric dating back 4,700 years was unearthed there in the 1950s.

As the silk industry has been transformed and upgraded in recent years, the city has introduced more modern technology to improve its silk processing. Now, a quarter of China's silk fabric is produced in the city.
