Hi @farshad hosseinpour 

Trello is currently available in the following languages:

English, Portuguese, French, Spanish, German, Finnish, Norwegian, Swedish, Russian, Polish, Hungarian, Ukrainian, Czech, Dutch, Italian, Turkish, Thai, Japanese, Traditional Chinese, Simplified Chinese and Vietnamese.

If you want to contribute you can reach out to the Trello team, but from what I am seeing here, at this time they are not translating any new languages:
