Boxing is one of the most popular sports in western countries and I like it. The spirit of boxing might be " never give up ". Amazing competitions, really!
If i say the one who has more powerful fists also has more chances to win in a boxing competition, will you doubt it?
But while we practice tai chi or practice tai chi pushing hands, the first rule would be " no strength ", and you should " give up " something somehow. Do you know why ?
According to the history record, there was once a tai chi master and one day a bird landed on his hand, and amazing thing happened at that moment: the bird can't fly away anymore! Do you know why ? Because when a bird want to fly, it has to jump first to get starting force, but the master didn't give that counterforce!
