Hello and thank you for your question, I look forward to assisting you today. My apologies but I have not read your original question. Can you repeat it for me please and I will try to assist you.
Do you manage your own router?
I was under the impression China had some internet limitations. Could that possibly be the problem?
I understand. My question is, do you think your internet service is blocking some of the web sites you are trying to access on purpose?
It may just be that a different DNS server assigned to your computer could make the difference. Do you think you can make that change?
I can send you a link to download a program that will scan and give you the best DNS server in your area if you would like to try it?
Check out DNS jumper and download the software. It may solve your problem. Let me know if you need assistance changing the DNS IP address.
I will try to remote in at around 8:00AM your time. Let me know if there is a better time for you.
