The Comparison Between International Workers' Day Doodles of Baidu and Google

Look at the two International Workers' Day doodles in the picture. Baidu's doodle is above, and Google's doodle is below. See the difference?

Well, I think this is kind of a metaphor: Baidu's doodle implies to build a wall, while Google's doodle implies how to cross over a wall. Since Baidu and Google are two internet websites, the wall could be interpreted as the well-known Great Fire-Wall of China, which is the very reality in China.
