The supplier produces or processes outside the general standards of the buyer (with higher strict requirements or precision requirements). This is relative. The products of different industries are different, so the meaning of so-called advanced customization will change constantly.

For example, in the jewelry industry and ceramic industry, the corresponding high-level customization is to change the color, style (modeling) and decorations (gold, silver, jewelry, etc. ). In the electronics industry, the corresponding advanced customization will not only be the colors, styles and decorations, but also adjust the internal structure and functions of products.

Extended data, such as:

Authentic: Authentic black swan purchased in official website, with light and smart outline and slender tail.

Purchasing: This so-called "authentic" profile is fat, with a big belly and a short tail! Hey, we doubt it!

A family: the appearance of a family's black swan seems to be closer to the genuine product than purchasing. The tail is sharp enough and the stomach is not fat. This is a good job.

B: B's black swan is bigger than the real thing, obviously with a big belly and a thick neck, which is simply a fat version! There are also some details of the curvature of the car body that are very different from the genuine ones.

C: This is more obvious. The shape is completely wrong, the whole is round, the details are missing, and the workmanship is not refined.
