Going to Harbin

This weekend my boyfriend and I will go to Harbin, his hometown, for one or two weeks.
Have you ever been to that city?
I really like Harbin. The first time I went there it gave me so many surprises. It's a Chinese city, but I learned much about Orthodox, Catholic, Christian, and even Jewish religion there. As a common citizen who grew up in mainland China, I was such an idiot about religion before, but Harbin gave me the first lesson and helped me to know a new world.
I feel lucky that my boyfriend grew up in this place, and I have many chances to come back here later in life, or even live here in the future.
Wish me a good trip! I will keep on giving Chinese lessons there!

I have never been to Harbin, but I do wish to visit China.

I only changed a few things. You understand compound sentences better than most Americans! I added the word religion in a sentence to provide a noun for your proper adjectives. Alternatively, you could have used proper nouns and left out the word religion, i.e., Catholics, Christians, and Jews. Lastly, I removed however from the last sentence. If you were looking for a word that is used informal conversation, you might try anyway or anyways. It's pretty common when chatting regardless of whether or not the word actually adds anything of value to the conversation.

Great work! I may look for you in the future so that I can take Chinese lessons from you!
