According to Foresight News, Jeffrey Yang tweeted that he has resigned from the co-founder, chief marketing officer and BD director of the modular computing layer and Raas platform Lumoz, and will no longer be involved in the company's affairs in any way. He said that Lumoz has recently changed its focus, and most of the work now revolves around copying and pasting content and artificially exaggerating indicators, and management has become increasingly chaotic. It is far from his own vision, so he decided to resign.
