Is there a limit to the size of a single document inserted into a MongoDB shard?

Question

MongoDB sharding + replica cluster mode, default chunkSize: 64MB; when the size of a single document inserted exceeds 100KB, the sharding will hang up, and the cluster will also hang up. I want to ask the master, does MongoDB have a limit on the size of a single document?
