The color of the lamp body is natural and smooth, and the color is consistent, uniform and firm throughout, and will not fade or fall off. Due to the coating, it is not easy to oxidize.　　2. Look at the workmanship: the workmanship of the all-brass lamp, whether it is a large-area outline of the lamp body, or a small part of the carving, a petal, a crescent, it can be said that it is seamless and seamless, all of which reflect the ingenuity of a skilled craftsman. 3.
