Usually if they can reliably tell its a VPN, they'll perform deep packet inspection which massively increases latency, or they'll throttle your internet connection entirely and you'll be at some tiny bandwidth until half an hour after you turn the VPN off.

Most VPNs attempt to disguise themselves as random 443 traffic these days and use custom or encrypted hand-shaking to prevent that being recognised.
Stuff like OpenVPN doesn't have a hope in China because it can be identified and then attacked/throttled.
