在这个世界上,最珍贵的东西都是免费的。阳光,是免费的。芸芸众生,没有谁离开阳光能活下去;然而,从小到大可曾有谁为自己享受的阳光付过一分钱?空气,是免费的。一个人只要活着,就需要源源不断的空气。可从古到今,又有谁为这须臾不可缺少的东西埋单?无论是贩夫走卒,还是明星政要,他们一样自由呼吸着充盈天地间的空气。 In this world, the most precious things are free. Sunshine is free. Mortal beings, no one can leave the sun to survive; however, from small to large, who had paid for the sun you enjoy a penny? The air is free. As long as a person alive, you need a steady stream of air. But from ancient times to now, who else pays for this indispensable thing? Whether they are pawnbrokers or star politicians, they are free to breathe freely and fill the air between heaven and earth.
