Off my vendor's list as well; pity because they sell quality zisha online, and finding it in this particular instance can be quite cumbersome and effort intensive.

Please don't assign malice to an action based on your misguided stereotype.
China is a huge place to explore, it has artists, computer wizes, chefs, and plenty of high school drop outs working hard for their living in factories.
Plenty of folks who grew up there are awfully bad at math. Like, can't figure out the tip in the restaurant.
