Who is Sun Nakayama?

Answer: He is the founding father of modern China, aka Dr. Sun Yat-sen, aka Sun Chong Shan! But Sun Nakayama is how the Japanese pronounce his name!

And as for our Dear Leader Chairman Mao Tse-Tung, he is called Mo Takuto! Imagine, dear Comrade Mo Takuto, let's go on the Long March! Haha!

Apparently the Japanese think the way their names (which mostly use Chinese characters) are pronounced in Chinese is equally funny.
