BEIJING \u2014 In the decade since the Chinese government began repressing\u00a0Falun Gong, a crusade that human rights groups say has led to the imprisonment of tens of thousands of practitioners and claimed at least 2,000 lives, the world\u2019s attention has shifted elsewhere. In the past year, as many as 8,000 practitioners have been detained, according to experts on human rights, and at least 100 have died in custody. Among them were Yu Zhou, 42, a\u00a0popular Beijing musician, and Cao Changling, the 77-year-old vice director of a paper plant in Wuhan,\u00a0whose bruised body was returned to his family\u00a0by the police last summer just as\u00a0China\u00a0was reveling in the glory of the Olympic Games. In recent months, scores of practitioners have been given long prison terms, including Zhang Xingwu, a retired physics professor from Shandong Province who last week was sentenced to seven years after the police found Falun Gong literature in his apartment, according to family members. The continued crackdown highlights the difficulty of eradicating a movement whose adherents stubbornly cling to their beliefs, but it also provides a window into the psyche of an authoritarian government that, despite its far-reaching power, remains deeply insecure. From the outset, the group, which at its peak claimed to have millions of followers around China, insisted that it wanted only legal recognition, not political power. But the country\u2019s top leaders were alarmed by the group\u2019s ability to attract a devoted following from so many citizens \u2014 from retired functionaries to pimple-faced college students. The decision to ban the group entirely was made after 10,000 Falun Gong adherents staged a silent protest outside the gates of Zhongnanhai, the Communist Party\u2019s leadership compound in Beijing, to complain about reports in the state-run media that the group said were defamatory. Security forces apparently had no advance knowledge of the demonstration, which took place on April 25, 1999, and they began treating the group as a threat to national security. \u201cEven a soccer team with an organization like Falun Gong might have produced the same reaction,\u201d said T. Kumar,\u00a0the Asia advocacy director\u00a0for Amnesty International. Although the propaganda juggernaut has eased in recent years, Falun Gong remains a toxic subject in China. Few academics will speak about it on the record, and the Internet is scoured clean of information that might be construed as sympathetic to Falun Gong, an amalgam of Buddhism, mysticism and qigong, the traditional exercise regimen that remains broadly popular here. For the Falun Gong devotees who practice in secret, the only glimmer of hope has come from a small but growing number of lawyers who have dared to take on their cases. Even if the legal efforts have mostly come to naught, until recently Falun Gong detainees were denied even the right to a lawyer. Among experts based outside the country, there is broad consensus that the government\u2019s efforts have not done much to advance its own interests, at least internationally, where it has been dogged by allegations that it uses torture to crush believers into submission. \u2018The excesses and the savagery have really lowered the quality of the government and harmed its reputation abroad,\u201d said Jerome Cohen, a member of the Council on Foreign Relations and an expert on Chinese law. \u201cThey\u2019re paying a high price for the cruelty to these people.\u201d According to Falun Gong followers and Chinese lawyers who take on their cases, that cruelty continues unabated. Among those swept up in the purge were Yu Zhou, the musician, and his wife, Xu Na. They were stopped for speeding in January 2008, according to their lawyer. After the police found Falun Gong materials in their car, both were detained. Ten days later, Mr. Yu\u2019s sister was told that he was gravely ill, the result, she was told, of a hunger strike complicated by diabetes. His sister, Yu Qun, says her brother did not have diabetes. She contends that he died at the hands of his captors. The family\u2019s efforts to investigate Mr. Yu\u2019s death have been thwarted by the police and prosecutors, who refuse to allow an autopsy or even issue a death certificate. Ms. Xu, who is a well-known poet and painter, was given a three-year term. \u201cI don\u2019t understand why this happened to them because they didn\u2019t do anything to break the law and they weren\u2019t promoting the group,\u201d Ms. Yu said. According to former detainees and human rights organizations, Falun Gong detainees are frequently subjected to harrowing abuse, particularly those who refuse to swear off their faith. Bu Dongwei, 41, a longtime adherent who spent three years in a labor camp, said he was forced to share a room with about 30 people, most of them petty thieves and drug addicts who were encouraged to abuse the Falun Gong detainees. Mr. Bu, a trained geneticist, left China in December and now lives in Los Angeles. Jonathan Ansfield contributed reporting.
