 Step 5: Configure calico and kube-proxy.
 
-Edge 节点加入时可能会自动部署 calico-node 和 kube-proxy，kube-proxy 会部署成功（但是 edgecore 的 log 会提示不应该部署 kube-proxy），calico 会初始化失败。为了避免上述情况，做如下操作：
 
 When an Edge node joins, calico-node and kube-proxy may be automatically deployed. 
 Kube-proxy will deploy successfully (but the edgecore log will prompt that kube-proxy should not be deployed),
