Chinese Americans seek roots, identity in ancestral country

Practicing kung fu, playing mahjong with villagers, singing karaoke with children, hanging out with strangers in a Chinese village they've never been to before - a group of San Franciscans feels right at home.

"It's a very moving and emotional experience for people to go back to their ancestral villages. It's a way that we can learn more about our connections to China, and at the same time learn more about our family histories," said Steven Owyang, an adviser and leader of Friends of Roots.

For nearly three decades, the San Francisco-based organization has taken about 40 such groups involving around 400 United States citizens to their ancestral villages in Guangdong province, from where many Chinese Americans have historically migrated.
