The spirit of China Tea Ceremony is "sincerity, beauty, harmony and respect": "harmony and purity", "quietness and sincerity", "Zen tea blindly", "elegance in walking", "extravagance and embellishment of ambition" and so on. In addition, there are many tea poems and tea couplets. Personally, I think it is better to use weeds in tea poems.
If it is a Japanese tea ceremony, then the two titles "for a while" and "respect without words" are the most appropriate.
In addition to proper calligraphy in the teahouse, elegant decoration is also essential.
I hope this helps you-
