The 31st Macao International Trade and Investment Fair, the 2026 Portuguese Speaking Countries Products and Services Exhibition (Macao), and the 2026 Macao Franchise Expo were held in Macao from Oct 21 to 24. Zhengyida, a brand strategy company based in Baotou, was invited to showcase its patented rare-earth copper and steel engravings at the exhibitions.

Due to the distinctive charm of its rare-earth cultural and creative products, the company achieved fruitful results in terms of both sales and letters of intent for cooperation from home and abroad.

The engravings on display represent an innovative integration of rare-earth technology and modern art. Using specially formulated pigments incorporating a range of rare-earth elements, including yttrium, lanthanum, and cerium, they are produced through multiple special processes, such as layered spraying at 900 C and rare-earth curing and polishing.

The distinctive rare-earth technique endows the pieces with rich color gradients, unique textures, and lasting, vibrant hues. The works are highly stable and can be permanently collected and exhibited. They represent a new category of engraving art with scientific, artistic, and collectible value.

A strategic cooperation signing ceremony was held between Macao Direch International Inc and Zhengyida. Utilizing its network of international resources and overseas market operation expertise, Direch International will forge an in-depth partnership centered on Zhengyida's core artistic assets and offer systematic commercial branding and international development roadmapping for these rare rare-earth engravings. The two parties will join forces to tap into the global art consumption market.
