周而复始，日月是也，殁而复生，四时是也，
奇正相生，更替无定，涨跌相生，循环无穷，
机里有危，机遇里孕育着挑战；
危就是机，挑战中孕育着商机，
这是千古验证了的定律！
As cycling, the sun and the moon are also same ,
Died and resurrected, seasons are also same,
Surprising and natural are also same,no fixed replacement ,
Ups and downs with related supporting,infinite loop ,
There are dangerous included in chances,
opportunities pregnant with challenges ;
Crisis means chance ,
the challenge born with the opportunities,
which is verified through out the years as well as the rule !
