SW11, the code name of the manufacturer of gold jewelry in Shenzhen, to put it bluntly, means that Kim Dae-fu doesn't produce gold jewelry himself, but he registered a fake trademark imitating Chow Tai Fook, bought the goods produced by others in a small jewelry factory in Shenzhen, and put the word "Kim Dae-fu" on it, saying that he is the same as Chow Tai Fook and sold it to the outside world.
