1948年12月31日,党中央任命彭真为北平市委书记,叶剑英为第一副书记兼北平军事管制委员会主任及市长。毛泽东在西柏坡亲自找叶剑英等谈话,嘱咐他们在接管北平的同时,要认真筹划好党中央移驻北平的工作。在当时全国尚未解放,天上有国民党飞机袭扰、地面上有国民党特务活动的情况下,将党中央领导及其机关从西柏坡迁至北平,确实是一件极为重大和艰巨的事。 On December 31, 1948, the Party Central Committee appointed Peng Zhen as Beiping Municipal Party Committee Secretary and Ye Jianying as First Deputy Secretary and Peking Military Commission Director and Mayor. Mao Tse-tung personally went to Yeibaien in Xibaipo to talk to them and asked them to carefully plan and plan the relocation of the CPC Central Committee to Peiping while taking over Peiping. It was indeed a tremendous and arduous task to relocate the leadership of the Central Government and its organs from Xibaipo to Peking at a time when the entire country was still not yet liberated, the plane was haunted by the Kuomintang in the sky, and the Kuomintang agents were on the ground.
