According to Qizhuang.com, Mingzhu Decoration has been focusing on formaldehyde-free home improvement, 3000+ customer case testing and 20000+ big data support for nearly ten years, and it is an advocate in the field of healthy home improvement in China. Through a number of patented products such as biotechnology, nanotechnology, negative ion technology, international environmental protection equipment, etc., targeted environmental protection products are adopted, and the whole process of detection and treatment is carried out before, during and after decoration. Covering all-dimensional and all-space such as basic equipment, materials, furniture and soft clothes, it is the first in the industry to put forward the concept of "space environmental protection" to solve the problem of superimposed pollution for decoration owners. According to the evaluation of the flag owner. Before the renovation, I found several decoration companies and made a comparison. I comprehensively compared the company size, designer's design, specialty and so on. And chose Qingdao Pearl Decoration Company. I had a long communication with the designer in the early stage, and the whole communication process was smooth and the explanation was very detailed, whether it was design or implementation. The final completion presents a perfect effect. From this, we know that Qingdao Pearl Decoration has a good reputation and will not deceive people.
