If you can transport more than one trip, there should be multiple solutions.

Provide a possible answer:

Assuming that there is only one batch of goods twice, it is equivalent to sending this batch of goods first, and then sending 9 ships together again, thus completing 36 packages of goods.

Then the total number of the first shipment and the second shipment is odd, which is 36.

Suppose the second shipment is one package per ship, then the first shipment is 36-9=27 packages, which is odd.
