New expansion of K8S POD has no traffic

The

deployment goes something like this: a svc deploys NGINX, then a svc deploys fpm, and then NGINX proxies to fpm, through svcname to complete the project of accessing PHP with nginx. The problem now is: I expanded the pod of fpm by half, but found that the request did not go to this new pod. Why? I just killed the svc of nginx and then created it. What"s the situation?
