First of all, taking orders is not very reliable. This is a marketing tool. Because the editing level is different, it is difficult for customers to distinguish, so many orders are pushed internally. When the technology is mature, orders will naturally be issued. Previous orders were basically dozens or one or two hundred low-priced orders. Fortunately, they can't make much money after hard work. Tempering is ok, but it is not necessary to do it for a long time. The point is that there is also a so-called black slave list (be careful). Simply put, the middleman makes the difference, you can't get a third of the order, and then many customers ask for that.
