This is wrong and the analogies are incorrect. The Chinese system today is based on meritocracy. The top leadership requires vast experience in successful governance before been considered. This prevents some clown who knows nothing from coming in and wrecking everything.
Entropy cannot be denied, no matter what system you attempt to implement. All things are subject to contradictions, error, and inefficiency that grow over time. It is why cancer forms, crime exists, relationships fall apart, why the universe will become cold and empty, and why time only moves forward. It is the second law of thermodynamics, after all. As such, whatever methodology you implement will be subject to Goodhart's Law, which says "when a measure becomes a target, it ceases to be a good measure," as even AI scientists find out.
The Song Dynasty had probably the best meritocracy and most efficient administration of all the Chinese Dynasties, but it didn't stop it from collapsing because it failed to take into account its defense. There will always be an oversight or some unforeseen consequence that occurs, like more recently the One Child Policy or letting the Real Estate Bubble grow too big, and eventually it will be one disaster too big to contain. No government or system is perfect, all things must rise and fall. Yet let's not be too pessimistic, but revel in the moment that we were born in an era to see the rise of China and likely depart before its eventual decline and fall. It is something many of our ancestors born in the century of humiliation were never privileged to see.
