The problem at three kingdoms towards the end was disloyalty to the emperor. Whereas cao cao understood. The eunuchs rebelled and took down the ministers then the emperor should have understood that it is time for anti corruption and a purge for the dynasty to last. Just like ming dynasty the problem was money. With all these money and nowhere to spend. with modern china china can trade to get the things they want spend the money when there are problems. Like a famine or social unrest for real. Under zhang ju zheng ming had money they taxed people and the ministers were able to maintain power. Under the eunuch wei or his name in ming dynasty the ministers were persecuted then the state or emperor should understand there are problems and can take their money. With colonialism and british we have ships and trade where we can use the money taxed to buy the things in case there are famine or big problems. The bottom line is falun gong lost in china they couldn't take control of the court at all the end result obviously they need to shut up and obey.
