There are common practice be it we call Qi or not that we are practicing. So, there are lots of things we both will agree because we both practice them.
How can one be good in Kung fu if one not even willing and cannot control one's sex life? it cant.
for me,
if one cannot 'eating bitter" I now a day dont even bother to show them the true practice. that is because kung fu is not taking Opium and have high. Kung fu is work to the point that confident and certainty become a nature. weak will people cant have good kung fu.
