Can I use the picture of Tiananmen Square as the background?

For example, the moving time-lapse photography of Tiananmen Square needs to take two shots for each brick, and the position of each shot has changed. To put grandpa Mao's portrait in the center, you have to shake the tripod head. This is the general composition. There are about 800 bricks in front of Tiananmen Square. I took more than 1600 photos, each of which needs to be re-composed. Because the shooting time is at night, it will not be greatly affected by time; Because the operation is simple, one person can do it.
