"One basket of pancake flowers can sell for 88 yuan ($13), which is 10 times more than the ordinary pancakes we used to sell," Xu said.

Pancake flower products have been keeping Xu busy, especially on special occasions, such as Mother's Day, International Women's Day and Teachers' Day, as many people look for a unique gift.

During festivals and holidays, Xu and some fellow villagers work long hours to meet demand. The pancake business she runs now provides jobs for more than 30 women.

"It's good for those who need to take care of the elderly and children," she said. "They can stay at home and come to work when they have time."
