Depends on the provider you get in China. And sometimes its just a hit and miss.
I tried all of the big players including ExpressVPN, Astrill, PureVPN and they all worked fine to some point. Today is such a special day, PureVPN isn't connection, no matter which server i choose. After i had massive problems with PureVPN a year ago i found Kaspersky Secure Connection which is decent priced, not too famous getting attention from the GFW and did work without a minute of downtime. Make sure you choose a VPN and open the account before you enter China, or else you will need a VPN to do so. Good luck and have a good time in China.
It's almost funny, no chinese skills required for a green card. In Germany for example it's unthinkable. First thing you have to do are language courses and tests. I'm staying in China for almost 12 years now, working legally, married for 12 years, having kids, 8 years i did not leave China and i can speak chinese. Year after year if have to do the visa- and work-permit application and at the same time checked if i would qualify for the green card. And everytime it's clear that the most important thing is money. You can tell them that you love China so much, haha... doesn't matter. First thing that matters is, that you bring money to China, second i guess is that you're some type of expert like atom-physicist, or else you have to struggle getting the green one. I also heard there is a new type of 5-year-residence permit now which they introduced in the Trade-City of Yiwu, but not sure if it's just a publicity stunt.
...and on the other hand, with 100k in your bank account as a foreigner, you will automatically meet the requirements for an investigation for tax fraud by the bank. Good luck everyone, i personally don't see the advantages of a chinese green card... except for not having to apply for a visa every year. Checked it out over the years while applying for visa, back in the days you also had to own a house.
