As of my last update in October 2023, Li Jinyu is indeed the current head coach of the Chinese national football team. However, I'm not aware of any specific announcement about him taking over offensive training or any coaching staff adjustment. The management and strategy changes in international sports teams can be quite complex and often involve multiple factors such as player performance, tactical needs, and overall team development.
If you have more recent information or context about this specific event, I'd be happy to try to provide additional insights based on that new information. Otherwise, if you're looking for general information about Li Jinyu's role and responsibilities as the Chinese national football team's coach, I can offer some background on his career and achievements.
