Lemme give you a counter example. Chinese copied Neato or irobot Roomba, their hardware was even superior and price is 30% as much, but ultimately failed as a product. Because the route planing algorithm is completely shit. You often found it stuck or running out of power.

Neato or iRobot does not sell in China, Chinese users actually pays extra to get one. And they are happily doing so.

The moral of the story? Chinese can not copy the soul of your product.
