All of which you said is true. Let's leave the more serious topics for another discussion, as you said.
On another note, some more famous turtles that I know of:
Sun Yat-sen/Sun Zhong Shan - father of the nation, moved to US at 13, then travelled back and forth between China, Japan, and US.
Qian Xuesen - father of Chinese rocketry, moved to the US at age 23 to study, moved back to China in 1955 after being a victim of the McCarthy communist witch hunt to work on the Chinese rocketry and space program.
That two figures are popular... but there are many other unsung heroes... examples... during WWII outbreak, many of the Chinese in Singapore and Malaysia went back to China to fight foreign aggressors, drive trucks for the Chinese troops and the such. Even as of now, many people are moving back to China for various reasons...
And as China grew in term of living standard, welfare and had much more established infrastructure, I am predicting that more will be going back to China in foreseeable future.
