向t3集合中增加一些文档，并直接访问三个分片节点予以验证标签分片结果。
t3集合中的文档列表：
mongos> db.t3.find();
{ "_id" : ObjectId("5bb2368cf116ff2bb6014827"), "name" : "a", "shard" : 1 }
{ "_id" : ObjectId("5bb23697f116ff2bb6014828"), "name" : "a", "shard" : 99 }
{ "_id" : ObjectId("5bb2369bf116ff2bb6014829"), "name" : "a", "shard" : 100 }
{ "_id" : ObjectId("5bb2369ef116ff2bb601482a"), "name" : "a", "shard" : 101 }
{ "_id" : ObjectId("5bb236a4f116ff2bb601482b"), "name" : "a", "shard" : 999 }
{ "_id" : ObjectId("5bb236a9f116ff2bb601482c"), "name" : "a", "shard" : 1000 }
{ "_id" : ObjectId("5bb236abf116ff2bb601482d"), "name" : "a", "shard" : 1001 }
{ "_id" : ObjectId("5bb236b3f116ff2bb601482e"), "name" : "a", "shard" : 9999 }
分别直接访问三个分片节点：
[root@coe2coe route]# mongo --quiet --port=27017

switched to db test
> db.t3.find();
