I am still amazed how many new words and idioms crop up all the time despite the four years I have been at it. I still consider my comprehension relatively weak. At the same time I know I am no novice and have some accomplishments to show for when it comes to language learning. I also adhere to the holy trinity so there is nothing wrong with that. So when I hear other learners of Chinese saying that their comprehension is strong, like you said in the other thread today I either don't believe them or I think something must be wrong with me.
When I listen to the news in my weakest foreign language, Spanish, I have certainly better comprehension than in Chinese, even though I never specifically tried to master Spanish news. Here are two short clips (some 1,5 minutes each) from the CCTV evening news which I just sampled randomly. Can you understand virtually everything without major effort? Could you transcribe it? I know I cannot, at least not all of it and certainly not without listening very carefully, but in a way I think as a C1 one should be able to do that.
