What are the main reasons for the rapid economic development of Japan and South Korea after World War II? What can we learn from China's economic development?

Mainly the industrial transfer of major developed countries in Europe, Japan and South Korea seized this opportunity! Later, it continued to move to the Asian Four Little Dragons, followed by Southeast Asian countries. Later, after China's reform and opening up, due to the huge advantage of cheap labor in China, it began to transfer industries to China! (including Vietnam now) Now China is transferring industries to other countries!
