How do you unmarshall nested json

Given dgraph res.Json:

"q": [
      {
        "city": {
          "uid": "0x51c7ebb",
          "name": "tsue",
          "postal_code": "0886"
        }
      },
      {
        "city": {
          "uid": "0x51c7ebb",
          "name": "tsue",
          "postal_code": "0886"
        }
      }]

type xRes struct {
		Q []struct {
			City struct {
				Uid        string `json:"uid"`
				Name       string `json:"name"`
				PostalCode string `json:"postal_code"`
			} `json:"city"`
		} `json:"q"`
	}

ures := xRes{}

err = json.Unmarshal(res.Json, &ures)
