The South Korean people are amazing workers and inventors. I have been very impressed with them over the years and I was lucky enough to live there twice for about 6 or 8 months at a time.It is impressive to see the technology of the factories of different products, everything taken care of so that their products are the best, and the consumer always complains about the price, it is to see how the product you want to acquire is manufactured, how much labor, how many people are involved in the manufacturing process, very beautiful video.
