The opponent does not know me;
I alone know him.
To become a peerless boxer results from this.
There are many boxing arts.
Although they use different forms,
for the most part they don't go beyond
the strong dominating the weak,
and the slow resigning to the swift.
The strong defeating the weak
and the slow hands ceding to the swift hands
are all the results of natural abilities
and not of well-trained techniques.
From the sentence "A force of four ounces deflects a thousand pounds"
we know that the technique is not accomplished with strength.
The spectacle of an old person defeating a group of young people,
how can it be due to swiftness?
