2、mongodb查询语句：
db.getCollection('regioncodes').aggregate([
{$unwind:"$children"},
{$unwind:"$children.children"},
{
$match: {
"children.children.id":"073103"
}
},
{$group:{
_id:{cityId:"$children.id",cityName:"$children.text",hesinNo:"$children.children.id",hesinName:"$children.children.text"}
}
}
]);
