From an ancient Chinese idom we learned the utmost kindness begins with filial piety。 百善孝为先 （bǎi shàn xiào wéi xiān）
The sustainable leadereship style is in question if one does know its meaning, actually the reason is quite simple:
How can you expect someone who honestly loyal and respectful if s/he does not even show the same attitude to respect her/his own moral ‘responsibility” to her/his parents?
How can you expect someone know how to behave as a team member if s/he does not even has a brother or sister? or does not know the respect to her/his elder brothers/sisters and kindness to her/his younger brothers/sisters?
