What about Shanghai Zhongxing Technology Co., Ltd.?

And ZTE Shanghai R&D center are two different things. Has little to do with ZTE. It was originally named Shanghai Wireless, and later it was changed to Shanghai Zhongxing to improve its popularity. The main holding group of this company is the bosses of ZTE marketing system, so the main profits of the company are taken away by these people every year. ZTE's investment in this company is very small (it will also take part of the profits every year, because the word ZTE is used, which is also a commission). Basically, ZTE will not attach importance to this word company, and will let itself die. From its establishment in 2004 to 2008, the company's performance was still very good, and the later period was a mess. The actual dark situation is long and complicated. Indoor coverage is originally the work of migrant workers, and Shanghai Zhongxing is also very poor. I suggest you read more industry reports and ask more.
