What did the Chinese use to transport food?

Because the king's wife, which was the Queen wants to eat cherries. Of course the King of the nation can't refuse. Because if he had refused; the labour will be asking him if the they became sick and dying of diseases will he care for them?So,the king decided that he will sent people from the capital of China to other foreign lands to find cherries for his dear wife and bring it back using horse slays.
