EDIT 2 My wife (native speaker) gave me some more hints:
- If you know some famous person with that character as family name, then Chinese people use that to give a hint what character
阮 is - e.g.
Ruan Lingyu de Ruan. (see Wikipedia)
- Another option would be to describe how to write
耳朵偏旁 and then
加一个元 which means
An ear and then add a yuan
My own answer:
天气的天, 文化的文 is good (like the comment already states), but actually there is a system to describe strokes, that some Chinese people use.
It is called
笔画 bi3hua4, which is like an phonetic alphabet for strokes.
This duckduckgo-image-search shows some of the charts that describe each stroke (as there are about 30 different strokes to describe)
I never learnt
笔画, so i cannot tell you how to describe your name in this system. You would have to name every stroke of every character.
Because this takes too long Chinese people do the same as everyone would do: They mix both approaches.
In your case for example they could use
天气的天, 文化的文 and if the listener doesn't understand the
文 the speaker would describe that character with
EDIT: The order the strokes are 'described' in would be the actual stroke order you would write that character in.
天 would be
Hope this helps!
