Modified / etc/docker/daemon.json, found that docke.io is still used when pulling data

NetEase image is used

{
"registry-mirrors": ["https://hub-mirror.c.163.com"]
}

but when using docker-compose up, why is the data pulled from docker.io not supposed to be obtained from 163s?

docker has been restarted
systemctl daemon-reload
systemctl restart docker
