Why isn't it 8: 00 in the morning but 3: 00 in the afternoon in founding ceremony?

Liu Changming was an adviser to the the Central Military Commission (CMC) War Department. 1949, 10, 1 that day, he and directly under the authority's comrades of the Central Military Commission came to Tiananmen Square. He knows the exact time in founding ceremony like the back of his hand, but out of secrecy, he just laughs at people's inquiries.

The news didn't come out until noon, and the opening ceremony will officially begin at 3 pm. Why is founding ceremony scheduled for June 10 at 3pm? Liu Changming recalled that when to hold a military parade was a very important issue. The final decision at 3 pm was also considered repeatedly.

Why? Mainly considering the problem of air defense. At that time, planes from Chengdu, Guangzhou, Chongqing and the Kuomintang all stayed, and their planes had a problem of operational radius. If we are early, it can go back after the bombing; We choose 3 o'clock, and we will be bombed back before dark to ensure the normal parade.

It is reported that the American-made B-24 bombers owned by the Kuomintang at that time were mainly concentrated in Zhoushan Islands. B ~ 2f bomber has a speed of 488 kilometers per hour, can carry 4 tons of bombs and has a range of 3,380 kilometers. The straight-line distance from Zhoushan Islands to Beijing is 1230 km, which is the B-24 that took off from there. After bombing Beijing, you can go back to Zhoushan Islands.
