Unity United Solidarity Cooperation in Chinese / Japanese...

團結/糰結 means to join forces, unity, united, union, combination, cooperation, or solidarity.

Regarding solidarity, this was part of the Chinese title used for the Solidarity Workers Union in Poland. In some circumstances, this can mean “hold a rally.”

While there's not a perfect match to the English word “unity” in Chinese, this word is pretty close. It contains the idea of joining forces and working as one. It could even mean rallying together to achieve a goal or defeat a common enemy.

There are several variations of these characters such as 团结, 団結, 團結, 糰結, etc. Modern Japanese will write it 団結. Just the first Kanji varies. Click on the image of that modern Japanese first Kanji to the right if you want this version instead of the traditional one.
