Sometimes, the Yin becomes the Yang, and vice versa.
During my grade school days (1960s), when someone pointed out that a piece of merchandise had been Made In Japan, everybody thought their product quality was something to jeer about, and be laughed at.
Then, came the 70s, and a small corporation called Toyota, it too, having been Made In Japan.
Pretty soon, the American manufacturers were not laughing about Japanese products, not at all!
