There's an upsurge of interest in Tomb-sweeping Day in the US as Chinese Americans honor their ancestors, Kelly Chung Dawson reports in New York.

Once a year, Chinese families gather at the graves of deceased relatives, bearing food, wine, joss sticks and paper replicas of worldly delights that their loved ones left behind. The celebration of Qingming Festival, or Tomb-sweeping Day, which falls on April 4 this year, is generally a private affair, but for Chinese Americans, there are numerous ways to celebrate, and a history that demonstrates a long-standing commitment to tradition. The holiday originated with the story of Prince Chonger (697-628 BC), a young royal forced out of the imperial court by a conniving concubine. Accompanied by a loyal government official called Jie Zitui, the prince lived in exile for three years before eventually ascending to the throne. Later, as king, he summoned Jie to his side, but when his previously loyal companion refused to accede to the request, the king burned down the mountain on which Jie lived to force him out. Overcome with remorse, the king designated a day on which Jie's memory would be honored.

Thousands of years later, the holiday bears little resemblance to its origins. But the sentiment remains unchanged: To honor those who came before us and made life possible.

"It is incredibly important to us that we honor our ancestors," said Tunney F. Lee, an urban planer and former professor at the Massachusetts Institute of Technology.

"For first- through third-generation Chinese immigrants in America, it continues to be an important annual tradition."

On Qingming, Lee's family visits the graves of his grandfather and mother, who are both buried in Boston. The family brings chicken, iced wine, incense and paper money. Each member of the family bows three times before the gravestone, lighting incense in honor of the deceased and pouring wine on the ground. In the past, food might have been left at the graves, but "we're practical people", Lee said, with a laugh.

Terry Abraham, former head of the Special Collections library at the University of Idaho and author of Chinese Cemeteries and Burial Practices in the Pacific Northwest, described the ritual as an exchange between the living and the dead.

"In a sense, the families are saying, 'We provide you with certain objects and representations of objects, and we are asking you to provide us with your support and good fortune,'" said Abraham. "There is an exchange taking place, and the common sentiment is that people who have died and have gone beyond to the next world are not really very far away at all. They're shadows around the corner, just outside the vision of your eyes, and you can provide them with what they need."

For some families, there is a deeply superstitious element to the ritual.
