if i want to do projection with my data like following

```auto
{
    "ProductName": {
        "WORLDWIDE": {
            "zh": "产品 1",
            "en": "product 1"
        },
        "CHINA": {
            "zh": "产品 2",
            "en": "product 2"
        }
    }
}

```

to

```auto
{
    "ProductName": "产品 2"
}

```

with some judgement then get specific data inside of `ProductName`
