Chenguang stationery stores exist at the entrance of almost every school, and it is through this chain marketing method that a large-scale student market is obtained. Chenguang started with gel pens in the early days, and now it has basically covered all kinds of stationery products, and writing tools are still mainly gel pens, ballpoint pens and mechanical pencils.

Including Chenguang, the domestic production of mechanical pencil manufacturers, itself started relatively late, the technology is immature, lack of innovation, at this stage in the process of imitating Japanese mechanical pencils, but still stay in the appearance of the product reproduction, movement technology and technology has no breakthrough. Therefore, many domestic self-produced mechanical pencils have relatively low materials, and automated production saves costs and fights price wars. For people who are not particularly pursuing writing fluency, or primary and secondary school students who are easy to lose or fall, the cost of buying these mechanical pencils is low, and the unit price is 2-6 yuan.

As a leading enterprise in China's stationery industry, M&G took the lead in striving for development opportunities and cooperating with Japanese companies to launch the Special Graph series and introduce advanced movement components and technologies from Japan. However, the production process cannot keep up, and quality control is the fatal shortcoming of domestic brands such as Chenguang, and many consumers feedback that Chenguang's mechanical pencils have nothing to show for themselves, and the product quality is actually very poor.
