The first method is simple and easy to manufacture. The patterns and inscriptions of the original mirror are clear and the lines are circulating, while the direct turning mirror, although the mirror type is the same, often has vague patterns and inscriptions and the lines are not circulating, which makes it rigid. However, some real mirrors are not well made due to their long history, and the inscriptions and patterns are vague. In the case of the same mirror type, pattern and inscriptions, it is also necessary to pay attention to the copper quality and massiness of the mirror body.

There are at least two cases in which the original mirror is used as a copy model. One is that the original mirror is completely imitated and engraved on the model according to the original mirror pattern pictures and inscriptions. Although the patterns of the bronze mirrors are different, the inscriptions and patterns are quite different. The second is that although the original mirror is used as a copy, the mirror maker also engraves patterns and inscriptions. Some of the patterns of the mirror are not in accordance with the age of the inscriptions. For example, the Han mirror is clearly combined with the common inscriptions in the Ming mirror; some of the shapes and patterns are not the same.

There is also a kind of splicing method of broken mirror: that is, to stick and mend the copper mirror. When the copper mirror is unearthed, there are few intact ones, most of them are broken or incomplete. The counterfeiter will weld the broken pieces into a whole, and then use another copper rust to mend the incomplete parts. Where the mirror surface is not smooth and there is green rust, they are all added.
