About MongoDB's shard cluster dynamically adding shards

I set up a shard cluster on the machine, which contains four shards, each of which is a replica set that can be routed to each shard when the program accesses it.
But today I added a shard dynamically when the cluster was running. There is no data routed to the newly added shards during the test, and my add process is this:
1, open a new replica set
2, run the Addshard command on an instance of MONGOs
As follows:

~~~~~~~~~~~~~~~~~~~~~~~~~ saw data on the new shards this morning. I test yesterday there is no data ~, I would like to ask you whether it is necessary for the Shard to take time. Or how to set it. Thank
