How to access internet after shutdown whonix?

How to access internet after shutdown whonix? It seems not possible for users in China to use Tor in any way. So I just want to shutdown whonix to save more RAM space. However if I did that, the internet would become not accessible.
I know that Qubes is security-oriented operating system. However It also sounds reasonable to give uses more rights to make their own choice of the security-level according to their situations.

Sorry for bothering. The reason why I created this post was that all apps became unable to access internet after shutdown whonix. However the problem is gone at the moment.
