Moving to the higher stage meant an extremely high technology and capital threshold and fierce competition, and it would probably take 20 years to get to the world's No. 1 position. As for aiming lower, although profits were relatively slim, and management more complex and arduous, it would only take five years to become the world leader.
向上走，技術及資金門檻極高，而且競爭對手強悍，恐怕得花 20 年才能取得全球第一；至於往下走，雖然利潤較薄，管理起來也更複雜而耗費心力，但只要 5 年時間就可登上全球龍頭寶座。
