the supplier's price includes the cost of goods plus the cost to pack the goods for international shipping and make them available to your appointed carrier in Ningbo, whether it's FedEx, DHL or a freight forwarder (better for larger shipments). In other words, FOB price is the China price only, and does not include shipping.
Ningbo is a port in the People's Republic of China, so the term means that the seller will pay transport to that city, and the buyer will pay from there onwards.
