China's army is looking into two big leaders. Their names are Zhang Youxia and Liu Zhenli. They think these leaders broke rules. This is a big change for the army. The army is changing now.
These checks happened fast. Now, the army's main group has fewer leaders. Zhang Youxia and Liu Zhenli are not working. Only Xi Jinping and Zhang Shengmin are left. Many others are gone too. Xi Jinping wants loyal people.
We do not have all the facts. But a paper said there were big problems. They broke trust. They also had money problems. This hurt the Party's control. Many think they were not good leaders.
Some think Zhang Youxia told secrets. He might have told the US about nuclear weapons. He also took money for favours. This could be with Li Shangfu. Li Shangfu was removed last year.
These removals are big for the army. People worry about the rumours. Fewer leaders could hurt the army's fighting. It also makes people wonder about China's plans. Xi Jinping is taking more power. The army's calm is important.
