“春还草阁梅先动，月满虚庭雪未消。”颈联景中藏心，最见功夫。春回大地，梅花率先绽放，是良知在困顿中悄然觉醒。月色满庭，残雪未消，是小我与私欲尚待克制。王阳明说“心外无物”，眼前的梅与雪，都是内心的映照。顺境不骄，逆境不馁，于冷清中见生机，于残缺中守清明，这便是我们最该学习的心学定力。

The same decomposition works in higher dimensions. For NNN random points on a sphere, the probability they all lie in a hemisphere is also N/2N−1N / 2^{N-1}N/2N−1. The argument is identical: anchor a hemisphere at each point, observe that each event has probability 1/2N−11/2^{N-1}1/2N−1, and verify that at most one anchor can work (the complementary cap is at least a full hemisphere, so no other anchor's hemisphere can straddle it). TODO: If I figure out how to add 3d visualizations to this website, I'll cover the 3D case
可以说，大包装在下沉市场的走红，背后折射出一个更深层的行业趋势：当走亲拜年越来越效率化，礼品的体积、重量与成套感成为“可见的诚意标尺”，消费者愿意为这种确定性买单；但与此同时，消费者的“拆箱核验”意识也在快速觉醒——体面可以在第一眼赢，但真实价值决定能不能做到长期赢。
