The bowing part of Japanese culture also learnt from ancient China.. modern China already don't bow while it's well preserved and strong in modern JapanMaybe political party not equals country and culture? Just like as good and dominant as pap is, it’s not equal Singapore? So Japanese maybe big on certain aspect of Chinese culture but not so on the current Chinese govt.
anyway I heard romance three kingdom and sunzi art of war sort of required reading for those jap middle management last time, not sure how true.
anyway anyway Japanese very big on certain aspect of Chinese culture since centuries ago, like they very big on Chinese 禅 which became zen and they also big on Neo-confucianist chinese like Wang yangming etc.
