There's a bit of a misunderstanding of what the silk road actually was, it was a web of different trade routes taking all kinds of things across Eurasia. You wouldn't be a trader going from China all the way to Europe, you would most likely be a camel driving trader in central asia selling your wares on to the next central asian trader who will take it a bit further west and so on and so forth adding a mark up at each stage. Your life would be very similar to camel driving traders from every point in history up until recent times.
