Is this really culture shock?

I started off this trip with the sole intention of getting culture shock. I did not know any Chinese Mandarin, I did not really eat “real” Chinese food, I just honestly did not know what I was getting myself into when I clicked the “submit” button when I applied for this dialogue. Although any experience is a new experience, I must say this one was truly one for the books.
Hearing so much about China’s rise to becoming one of the important countries in our time, I was expecting a lot more than I should have. I was expecting a developed place with skyscrapers, and international restaurant chains all around. I was completely wrong. I was surrounded only by Chinese (in every sense of the word). Finding a restaurant where they did not sell Chinese cuisine was a real tough task but I was in dire need of anything that was not noodles.
Besides problems in finding foods that would go well with my system, I had an interesting revelation while being here that people make a huge emphasis on bilingualism. At first, I thought this concept was cool since I, myself, am bilingual but as the weeks went by, I started to notice that none of the Chinese people that I was meeting were really interested in Hispanic culture. If I said something in Spanish or mentioned a cultural difference/similarity between the cultures, I would just get nodded off with an “okay.”
Seeing that this was becoming a trend, during one of my classes I asked my teacher how to say Spanish food. She responded back to me with the Chinese phrase for “Spanish food.” Although it was correct, she thought I was talking about Spaniard food. I quickly made her see that I was trying to say Latin food, since we were on the lesson on what we missed from home. She was really confused for a while but only came to me with “Western food,” stating that anything in the American continents was considered “Western” to the Chinese. I, personally, was disturbed. As someone from Hispanic descent, with pride of where my parents’ roots came from, I felt that Hispanic culture was largely overshadowed.
China is seen as the fastest emerging marketing in today’s time but what worries me is if they can catch up to learning about the world it is surrounded by. So my main question is if this really is culture shock? I feel as though culture shock can be interpreted in many ways but if the questions are: have I been homesick? Have I wanted to go home on an impulse? Have I cried? Has something happened that has made me furiously confused? Yes. Yes. Yes. And yes.
Long story short: do people do things here that are different from America? Not so much as you would think. Do I feel like, culturally, they have really made me conflicted? Oh, yeah…
