After a few days in China, I give an account of what happen.
Although StrongVPN works in China, it is a hair pulling experience, connection is very unstable, sometimes never be able to connect, and sometimes although connected but there is totally no traffics. Once in awhile may get connected to Google it is very slow, even on high speed hotel internet. When not in hotel and when it is trying very hard to get connection, it use up a lot of data, my $10/100MBytes get use up very fast. For sure www.strognVPN.com
is also blocked in China.
Almost giving up and stress for not able to get a good connection to Google to do my business (my LOB booking is based on GoogleDoc), out of desperation, I search the net (using MSN because Google was hard to connect) and found expressVPN. Sign up and paid another USD12+, it works very well. Better still, it provides the Android software in APK file for me to install in my google phone, since I was not able to access Google playstore.
It has been working very fast and well.
