Story of time 

The real strong are battle-hardened, the road is bloody, if you are now in a peaceful environment, then you may be a sheep, one day will become the Wolf’s prey. The real strong force himself when helpless, even in the stormy days, will not beg for mercy, because he knows how to rely on others, equivalent to their own fate to the hands of others. A man who can get out of the battlefield is never one who is easily defeated.
