From the time of the numen brand's birth, innovation was the basis for its foundation, which allowed the classroom to leave behind dust contamination, and a new generation of environmental teaching aids, such as hand-written liquid crystal screens, electronic platforms, interactive electronic whiteboards and environmentally friendly water chalk (i. E. Dustless liquid chalk), also guided the way to completely subvert traditional teaching methods. Water pens appeared in the market before the numen brand was read, but for reasons of technical content, these products were not popular in marketing. The market for reading numen-friendly water pen products has quickly opened up the market for green teaching aids, with great advantages over other brands. In order to create an excellent national brand and to set the stage for the leadership of the numen environmental classroom, "brand one", hu zhi xin is committed to creating numen as a new and emerging company that specializes in research and development, production, marketing, and servicing new green environmental education products. Based on guangzhou, the southern economic centre, the company works to develop a web-based marketing pattern based on high-quality supplier selections, with a focus on direct marketing in the province and off-site。
