Your scheme is merely a castle in the air. 你的计划只不过是空中楼阁。
But Violet drifted alone among the lilies, dreaming of the daring duck who would take her to live in the moat of a castle. 小紫却在荷叶间姗姗游过，梦想着可以带她生活在城堡护城河里的亲爱的另一半。
Fortunately, even if you know nothing about business, you can begin with a dream, a castle in the air, and then build a foundation under it. 幸好的是，即使你对做生意半点不通，你还是可以从你的梦想出发，一个空中的城堡的画面，然后就在这个梦想中开始建立现实。
