Anti-Japan protesters hold portraits of the late Communist leader Mao Zedong, Chinese national flags, and a poster that reads: "Sept. 18, National Humiliation Day," while marching on a street outside the Japanese Embassy in Beijing Tuesday, Sept. 18, 2012. The 81st anniversary of a Japanese invasion brought a fresh wave of anti-Japan demonstrations in China on Tuesday, with thousands of protesters venting anger over the colonial past and a current dispute involving contested islands in the East China Sea.
