Can the descendants of the Ming royal family apply to reclaim the ownership of the Forbidden City?

You can't. Because although it was first built in the Ming dynasty, everything it has the right to inherit is dead, and other branches have no right to inherit. What's more, the current Forbidden City was built in the Qing Dynasty, so the ownership belongs to Aisingiorro. When the Republic of China was established, it was legally guaranteed that the Forbidden City was still Puyi. After the founding of New China, it was all owned by the state. When can someone embezzle state property aboveboard?
