Mongol traders is carrying 4 resources instead of Only Gold. How?


In this image, you see, that mongol trader in AOE4 is carrying all 4 resources. How is this possible, as Traders can only have Gold as production. Can someone explain ?

mongol hasn’t wall ,so have more resource.more dangrous more resource

This is a mongol-specific bonus called the “Silk Road”; I forget the details, but basically if a Mongol is able to pass a certain threshold of active traders (10 maybe?), all their traders gain bonus food, wood, and stone
