He relies on word of mouth to sell his work but given the village has no paved road, there is little passing trade and the village remains off the tourist trail that is beginning to emerge in the valleys below.
Long considered opening an online shop on Taobao, an online commerce site similar to eBay, but feared his work would be copied.
"No-one knows about us. We hope to develop our own Kongbai brand name," he says.
To reach a wider market, Long has experimented with new designs.
Traditionally, the silversmiths in the village, home to members of the Miao ethnic group, made the elaborate head-dresses and hair pieces that are worn by women on festivals, weddings and other special occasions.
Using knowledge gleaned during his time outside the village, Long turns traditional Miao symbols like butterflies, fish and drums into modern pendants, charm bracelets and anklets.
"We have to follow the trends. It helps promote our skills as traditional craftsmen."
But it's not a get rich quick strategy.
His family is reliant on their land for food and a dry spell this summer means that some crops have failed.
Monthly profits from silver-smithing are less than a third of the 7,000 to 8,000 yuan (US$1,200) he earned at the shoe factory.
He also worries that tourists buying Miao silverware can't tell the difference between machine and handmade work and won't be prepared to spend the extra money on the handcrafted pieces he produces.
Nevertheless, he's hopeful his efforts to revive his village's time honored trade will pay off and allow his 15-year-old son to avoid the factory towns and become the thirteenth generation of his family to work as a silversmith.
"I don't want to be the last," Long says.
