Criteria of making an acceptable word/character in Chinese
There is a yearly contest in Japan for creating new kanji. Last year, the winner was a new character for &quot;social distancing&quot;

A clever play on the character 座, meaning &quot;to sit&quot;, where the two 人 &quot;people&quot; are moved apart.
Some other interesting ones:

&quot;Sign language&quot;, taking the character for &quot;sound&quot; 音 and replacing the 日 with 目, which means &quot;eye&quot;.

Taking the character 会, which means &quot;meeting&quot; and replacing the bottom part with a Z, to mean &quot;online meeting&quot;.
You can see all the entries and their meanings (in Japanese) on their website.
