(" '人道中国' Humanitarian China [headquarters: San Ramon, Calif (16-mile air distance east of Oakland] 是周锋锁 [Fengsuo ZHOU, which is the order he lists his name] 等人在2007年联合建立的为中国因社会、政治和宗教原因遭受不公义对待的人提供人道支持和援助的组织。而 '中国民主教育基金会' [Chinese Democracy Education Foundation (CDEF)] 则是组织促进中国民主法治、维护人权自由的教育活动的机构，总部在美国加州" (Hayward, Calif; just southeast of Oakland))
Zhou "spent two days in the capital visiting Tiananmen Square and a police detention center where several of his friends are being held before the authorities caught up with him Tuesday evening, he said. After 18 hours of interrogation, he said, he was put on a flight to the United States
"With [this] one exception, none of the other students on the 21 most-wanted list who went into exile have been allowed back into China
"Mr Zhou said he had expected to be refused entry when he applied for a 72-hour visa upon arrival at Beijing International Airport this week. 'It was a complete surprise when they gave it to me,' he said by phone Thursday afternoon, several hours after returning to his home in San Francisco.
"Mr Zhou, then a physics student at Tsinghua University, was turned in to the police by his sister and jailed for a year. In 1995, he left for the United States and received a business degree from the University of Chicago. He worked in finance [in San Francisco Bay Area], but more recently, he has been devoting time to political activism.
"This was Mr Zhou’s third trip back to China. He said he had never publicly disclosed the two previous visits, in 2007 and 2010, because he did not want to alert the authorities to what would seem to be a lapse in security. He said he tried to travel to mainland China from Hong Kong last year but was denied entry.
