Whats the best Vpn for china?

I am going to china in a couple weeks for about a month. I need a vpn for 2 devices which are both iOS and mobile. I need a Vpn to access apps like discord, youtube, google, etc. Currently I have been looking at express and nord vpn but I've seen many reviews saying they don't work. What Vpn do I go for that protects data, fast connection, and works in China?
