Today is a special post to temporary 'sayonara' to my brother & my cousin who went back to Asia

Since we still have family business in Asia, my youngest brother goes back & forth to be there.
He likes to compare east and west. I think it is just a Yin-Yang Tao. Nothing is clear cut. Chinese saying says
“阴中有阳，阳中有阴” meaning there is yin within yang; there is yang within yin. There is no absolute yin or yang. Any phenomenon is relative terms, not absolutes by comparison with something else.
