Dong in Chinese / Japanese...

東 is the direction East in Chinese, Japanese Kanji, and old Korean Hanja.

In Japan, this can be an abbreviation for a kind of six-stringed zither, or the personal name, Yamato.

東 is used as a suffix for many words in Asia. In fact, it's part of the CJK word 東方 meaning Orient or Oriental. The word 東方 more literally translates as “Eastern Kingdoms,” “Eastern Countries,” or simply “The East.”

動 is the only Chinese/Japanese/Korean word that can encompass the idea of “dynamic” into one character.

動 can also mean:
to use; to act; to move; to change; motion; stir.

In the Buddhist context, it means: Movement arises from the nature of wind which is the cause of motion.

The key point of this word is that it represents motion or always moving. Some might say “lively” or certainly the opposite of something that is stagnant or dead.

Note: In Japanese, this can also be a female given name, Yurugi.

冬 is the word/character used to describe the Winter season in Chinese and Japanese.

It also means winter in Korean Hanja, though a second character is usually added in Korean.
