I think more diffcult for me is understanding ,because it is related to more about the culture 

I consider that it is speaking. I have trouble in expressing my idea to other. 

hi everybody,for me i think that understand english in a general case is more difficult than speak specially because each english speaker has their own pronuntiation according to their culture.In fact,there is so many english speaker nowadays all over the word and sometimes when two persons who have different origins have a conversation,the difficulty to communicate is more stressed when you come to the understanding..sometimes i have this problem when i practice with one of my chinese friends for instance...
