Have you seen this character?
This is “CHA (tea) ” written in Japanese Kanji. (*Kanji is often translated as Chinese character.)
Broken down into smaller parts, the character of tea can be implied “Human beings are between grass and wood”. That is, the word of 茶 preaches that people are embraced and protected by the blessings of nature. Tea is one of them.
There are various views of the origin of the character, and especially I like this interpretation. Tea has been with us for a long long time.
