GREEN BAY, Wis. — Chong Xiong, 16, grew up watching the Packers on television following Sunday morning services at his church on 3rd Street, where men and women consumed with the Holy Spirit find themselves kneeling and weeping at the altar during the pastor’s most passionate sermons. Xiong’s family is a part of the growing Christian subset of Green Bay’s most unexpected minority—the Hmong, a group of mostly refugees displaced from Southeast Asia by the Vietnam War and its aftermath. When Xiong entered high school, he got his first opportunity to attend a Packers game, not as a paying fan but as a volunteer, sweeping up discarded beer cans and bottles at the gates and throughout the concourses.
