To keep the “congress” proceedings secret, the observers said, the “deputies” picked up from “districts” and “units” on China mainland all gathered at Chung-nan-hai, a district where Mao Tse-tung usually resides. They went to the “People’s Hall” through a tunnel. After the “congress”, they came out through the same underground passage. Foreigners, including reporters living in Peiping could see the “People’s Hall” lit up at night during the meeting, but found no buses and sedans parked around the "hall". The truth was not bared to the world until after the regime itself issued the news on the "congress."
