Does it make sense to live in China?

Sorry the title of the post it is a bit weird. I couldn't find what to write to title.

Hi, I'm 23 years old. I'm living in Turkey. I am a university graduate from the foreign trade department. I work in the machinery industry (international trade). I have a job that can be called neither good nor bad. I met a Chinese girl through work. She stayed in Turkey for about a month, it was a good opportunity for us to get to know each other. We fell in love and have been talking for months. She lives in guangdong provience, so if I go China I will be there with her.

The conversations are now starting to get to places like living together. As you know the economy is bad and living conditions are difficult in Turkey. In Turkey the minimum wage and the lowest house rent are the same amount. Almost all of my friends living with their families because leaving house is too expensive. Also, I am an atheist, and there is no great pressure on atheists by the state in Turkey. But the peoole in turkey is so judgmental about this and I'm not happy about that.

Living in China makes sense from an economic perspective. But issues like freedom of expression bothers me. Even for the simplest task VPN is required. I know in turkey you also need vpn for a lot of things but in China it's too restrictive.

I know a Turk who lives in China and has a Chinese wife. I plan to consult him in the future, but before that I wanted to ask you. What do you think about living in China? How were your experiences? Is there any advice you can give regarding my situation? What can I do if I go to China? What can you say about Guangdong region and working conditions, job opportunities?

Please I need friendly advice from people who have lived in China
