At the eighth China Intangible Cultural Heritage Expo in Jinan, Shandong province, in October, Li and her co-workers' pictures were a big draw.

"Many museums have shown interest in buying our work or in selling it for us," says Jia Zhiling, a manager at the Bailang forest culture company.

Earlier this year, bark pictures made their way to the United Kingdom and Ireland for the Chinese Lunar New Year celebrations, Jia says.

Li has also come up with kits for amateurs to enjoy a taste of the art form's beauty.

"It has been a hit with travelers, especially those on learning tours," Li says.

Looking back, she says that she is delighted that bark art has evolved from a record of life and work in the forests into one of the most popular local tourist souvenirs.

"It is a gift from nature. I will continue to infuse a touch of modern style into its authenticity," she says.
