After understanding the history and classification of design patterns, how should we learn design patterns? Before learning the design pattern, readers must establish a kind of consciousness, that is, the design pattern is not only a method and technology, but also an idea and a methodology.

In order to ensure that insects will obey themselves, flowers and insects maintain a sustainable and win-win cooperative relationship. Flowers will be grateful that insects can find their other half. They will give sweet nectar to their hands. This substance is especially important for the growth of insects, especially larvae. Scarabs, butterflies and flies are heroic pollinators, but unfortunately, they spend most of their adult life mating, laying eggs and eventually facing death. Therefore, for insect-borne plants, these insects are not the best choice for pollination. Bees, on the other hand, are loyal allies of insect matchmakers, because on the one hand they have to take care of their offspring, and on the other hand they have to use flowers to brew their own food-honey. Bees will consume some nectar and pollen, but at the same time, they will also assume Cupid's responsibility and rush for the reproduction of thousands of plants.Zero Day InputPattern correspondence:　　Phil到处搜寻其他幸存者却一无所获，但无论如何他都不会放弃，因为他坚信自己不是一个人。如果有一天他终于遇见了她，那就太妙了！
