如果人類的物質生活一年比一年富足，蛋糕的推出越來越精緻，科技越來越便利，同時沒有前人種樹就不可能有後人乘涼，那麼我便可以肯定“富有”的人生，肯定是由熱愛吃苦的前輩，那群帶有苦味的食客開創出來的。

If humanity's material life becomes richer year by year, cakes become more and more elaborate, technology becomes more and more convenient, and at the same time, without earlier generations planting trees, later generations would not be able to enjoy their shade, then I am sure that the "rich" life must've been brought about by our industrious forefathers, those who were unafraid to taste the bitterness of hardship.
