If a proxy is an option for you, look into SocketPro.
It has split tunneling by default, can control the domains that need to be send through the proxy and traffic normally. It’s faster then any VPN I ever used in China. No buffering on Youtube videos with the Vietnam and Korea servers.
I am a very happy user for over the last year and a half and have not used a VPN since.
