There are some invisible companies in China. Some are quit big. For example there's a mobile phone company called TRANSSION HOLDING in Shenzhen. In Feb it's mobile phone production is No.2 in China, next to Huawei, more than Xiaomi which is No.4. It's brand is even unknown inside China. How such a company is unknown even within China while producing so many phones? Because its market is in Africa. Its brand, Tecno, is the No.1 mobile phone in Africa
