You are welcome, Phil.
<em>"Only there are no subtitles in real life, so how do people cope with that?"</em>
Your concern doesn't contradict what I said. People's mind can be conditioned to watch TV shows with subtitles, and so that can also be conditioned into living a real life without subtitles in equal measure. Of course, I am generalizing here. There are exceptions. Some Chinese people might have a strong tendency feeling and thinking like westerners.
You can ask your mainland Chinese mentor or teacher this question: what is the relationship between consciousness and objective things?(意识和客观事物的关系是什么?)If they are not a rebellion, they will give you the same answer which is taught in school: the consciousness is the reflection of objective things in the human brain. The essence of the world is the material which exists independent of the consciousness.
From a western perspective, it is normal that you found what I said is unacceptable. Based on your American fundamental principle, you might think this mindset devalues the independence of a person's life. We ought to think for ourselves so we need to practise our five senses in a way according to the nature of things. The purpose of life is to find and express ourselves derived from the 'things-in-themselves' in the sense of genesis.
In practical life, most Chinese families might have one television only to watch together. The older generation might have hearing problems or they didn't have the opportunity to get proper education for speaking Mandarin back in their time, so watching TV with subtitles is clearly good for them now. As long as the younger generation can't turn off the subtitles, they are lovely.
<em>Here in the West, many of my students say they started learning English in order to watch original movies and programs without subtitles. That probably seems crazy to you — what do you think?</em>
I don't think this is crazy. I myself sometimes even turn off the audio while watching English TV shows.
