One of the most popular Chinese movies is “San Guo” or “3 Kingdoms”. This is historical fiction. There was a battle then just as there is still a battle now…in Taiwan.
From 1920 or so, a few groups, but mainly the CCP and the KMT (KuoMingTan) were battling for control of the mainland. The KMT lost, and so they fled to Taiwan. This battle is alive and well today.
In fact, rumor has it that Xi Jingping’s father whom served as the head of Canton wanted to secede in disagreement with Beijing and because there is still a history of Canton standing on its own.
China is fragmented still today.
