Speaking of children's spaces, whether kindergartens, early education centers, or indoor children's playgrounds, the first thing we focus on is environmental protection, material and equipment quality, and whether they will affect children's health. For professional children's space design companies, this is equally important and a basic principle. Yujian Future has a dedicated materials department to inspect all related materials and cooperative manufacturers. The first stage is the review of environmental quality certifications, and through professional equipment testing, we ensure quality for investors, consumers, and children.
