Perhaps you missed that reference to "long-scale chinese time" already in the reply meme?
And "thousands of years" is actually incorrect. The longest Chinese dynasty was the Western Zhou at 496 years. Many others - as the current party figures are always aware - lost the "mandate of heaven" much much sooner than that.
There is a good Chinese proverb that when short men cast long shadows, it is a sign that the sun is beginning to set.
The day is not over yet, and this still causes them sleepless nights.
