Recently, Brother Cat has often heard the phrase "After Yashan, there is no Huaxia," and it seems to spark heated debate every few years.

Some people believe that after the Battle of Yashan in 1279, the Song Dynasty fell, and for the first time, central China entered a long period of rule by a foreign dynasty, thus ending the traditional "Huaxia civilization."
But others think the phrase itself is an emotional expression.
Because whether it was the Yuan, Ming, or Qing dynasties, Chinese culture has always continued—Chinese characters didn't disappear, Confucianism didn't disappear, poetry, calligraphy, and painting didn't disappear, and civilization itself has been constantly integrating and developing. On the contrary, other ethnic groups were assimilated by Han culture.
Perhaps what is truly worth discussing is not "whether there is still Huaxia after Yashan,"
but rather,
What exactly does Huaxia refer to? A dynasty? An ethnicity? Or a culture?
If Huaxia is understood as a culture, then can civilization end with a change of regime?
Do you agree with the statement "After Yashan, there is no Huaxia"?
