Hopes for tourist surge after locals embrace 'Mosili'an' effect

MOMCHILOVTSI, Bulgaria - The Bulgarian villagers hunker over their books, struggling with their Mandarin words and characters. But they are not going to China - China is coming to them. Because of yogurt.

"It's difficult. You have to be quite tough not to give up," said Tsvetka Radkova, 66, as she puffs and pants in the classroom in the village of Momchilovtsi in southern Bulgaria.
