As Chinese classrooms turn digital, chalk seems out of the picture.
But for Liu Dafeng, the largest chalk manufacturer in Liuyuan village, in Hubei province, where 80 percent of chalk in China is produced, it's just another chance to move up the industrial value chain and generate more profit.
Chalk used on projection cloth in multimedia classrooms is powder-free and environmentally friendly," Liu said, adding that "chalk products can be used in other industries like clothing and machinery. "
To him, alternative uses for chalk like hair dyeing and toys are no longer something new.
To date, Liu's company manufactures over 300 types of chalk and produces 15 billion units per year on average, with 80 percent exported to other countries.
Talking about his plans, Liu said he will turn Liuyuan village from the home of chalk manufacturers to a chalk-themed tourism destination.
The history of chalk manufacturing in Liuyuan village dates back to the 1980s when the village was discovered to have an abundance of calcium carbonate, the then major ingredient of chalk.
He said there is likely to be a museum, and workshops in the village for children where they can make cartoon statues out of chalk.
"People thought I was crazy to leave a decent job in a big city to go back to selling chalk in a small, remote village, where my parents had worked hard to pay for my tuition so that I could leave," he laughed.
I planned to sell chalk online and set up a broader sales network through the internet. "
