Revolutionary in Chinese / Japanese...

切格瓦拉 is the name “Che Guevara,” as written (transliterated) in Mandarin Chinese.

Once revered by Chinese people as a Socialist rebel, he's now just a historical figure that school children briefly learn about in China.

切格瓦拉 is because China used to be a truly-Communist/Socialist nation, and thus, other Communists and Socialists were heroes.

In modern China, with its free-market economy, those former heroes fade a little.

We are not offering the “Che” character alone, as few would associate it with Che Guevara, so you need the full name to be clear (minus Ernesto, which is his real first name).

This is the Spanish family name, Guevara.

Probably the most famous person to have this family name is Ernesto “Che” Guevara, the Cuban / Latin American revolutionary.

革命者 is a noun, meaning a rebel or revolutionary in Chinese (rarely used in Japanese Kanji).

The first two characters mean “revolution” (specifically a political revolution or revolt).
The third character means “person.”

紅 is a single character that means red in Chinese, Japanese Kanji, and old Korean Hanja.

The perceived meaning of this character can be ambiguous. Most will see it as the color red but it can also mean Communist (just like it can in English). In Japanese, it can be a female given name “Rena,” or refer to red silk lining. In Chinese, red is a good luck color, and can refer to a bonus or revolutionary.
