The "Miao-Tuan" Group started off on a two-month "Walk to Beijing" trip in February, 1997, to commemorate Hong Kong 's return to China. The group traversed through Guangzhou, across the Yellow River, to Mao Zedong's birthplace, to Tiananmen Square, and finally to the Great Wall. The trip provided a unique way of viewing the post-1997 relationship between China and Hong Kong.
