Hello. It's been a while.
You have completed the wire guard configuration. Good penguin.
I also want to configure wire guard multi.
Although two peers are configured, only the IP address of one peer is displayed. 192.168.1.1/32 outputs 222.114.48.XXX 192.168.1.2/32 outputs 121.185.53.XX Please tell me how. Thank you !

Break the wg0 into wg0 and wg1. You cannot route properly otherwise.

Need to add wg1 on both server and client side?

On the side that you showed us. The other side doesn't care how is the peer interface named.
