The zzzz statue is crafted using the intricate lost wax casting process. In this method, the skin portion of the statue is meticulously cut out and replaced with a variety of metals, such as crystal, lapis, coral, or even a combination of these materials, to create a striking visual effect. Meanwhile, the remaining sections of the statue, including the body elements like the clothing, the lotus base, and the jewelry, retain their original copper material. This unique combination of metals and craftsmanship highlights both the skill and the artistic vision behind the creation of the zzzz statue.
