Is Miracle Qijia and Wistron a System?

Not a systematic one. Qijia Communication (Kunshan) Co., Ltd. and Miracle Yongchang Communication (Kunshan) Co., Ltd. are listed companies with wireless communication as their core, but they are independent companies. Their own system. Wistron, formerly known as the DMS department of Acer Computer Co., Ltd. 198 1, is positioned as a professional ODM supplier. Qijia and Qiji don't belong to the same company, let alone a system.
