Factories in and around Guangzhou are renowned for mass-producing a myriad of products that are exported the world over.
Lesser known, however, are the few remaining families in this city who continue to make high-quality, hand-crafted products.
The Guo family, which has been crafting flutes since before the revolution, is one of those clans.
Nearly 50 years ago, Guo Yi Zuo operated Lingnan Guanyue She, one of the largest flute factories in southern China.
These flutes, known as dizi, are classical wind instruments that produce a raspy sound, created by a vibrating piece of rice paper that is sealed over one of the instrument's holes. The dizi is commonly used in Cantonese opera.
The family also produces other kinds of flutes, such as xiao and Japanese-style instruments known as ciba.
Today, Guo's two sons, Da Qiang, 38, and Da Ming, 33, carry on his legacy. Tucked away in a back alley, off Hui Fu Xi Lu, the two sons and their father continue to craft flutes from a variety of woods, such as black sandalwood, suanzhi and bamboo.
