Just a year ago, we saw the question of "the essence and dross of history and the present" one after another. For a time, some people and things were immortal in history. Many aspects are inconsistent with our current social environment and the spirit of the times. For example, people in Lu Xun's "From a Hundred Herbs Garden to the Moon in San Tan" don't protect wild animals, and the father in Zhu Ziqing's "Behind" doesn't obey traffic rules, and Wang Xizhi washes the pond and pollutes the environment. There is a loud call for denial. This problem lingers in my mind, so I have to discuss it and talk about my superficial views.

Human beings have created heaven and earth from Pangu, people and things in nature have gone through a process from birth to death to continuation, and human society has gone through a process from birth to extinction to regeneration, hasn't it? Nowadays, human society is prosperous and changing with each passing day. There are many factors in this, but the common feature of human beings at each stage is to constantly absorb valuable spiritual and material wealth in the process of human society, sum up the experiences and lessons of ancient and modern society, so that the process of human society can continue to advance, human beings can live in harmony with nature, constantly explore the truth, and make human life better. The process of human society is like a stream flowing into the sea, and the growth of human beings is like the scenery in four seasons: spring, summer, autumn and winter. Only by going through every process in a down-to-earth manner can we reach the treasure of mankind. From the times of Wang Xizhi, Lu Xun and Zhu Ziqing to the present, Shenzhou 5's contribution to space travel is the product of human progress, the result of continuous exploration and the scenery of nature. Only by continuous exploration can we find the essence and valuable experience to promote the progress of the times. Gold was found from the bridge to the other side of the river, but do we deny the role of the bridge? Maybe the bridge doesn't work now, but without its connection, how can we reach the other side of victory? Some people think it is necessary to absorb the essence, discard the dross and try to make them disappear from people's sight. I think these dross, once the essence, can no longer be advocated, but they can't be completely denied. Without them, we can't explore the truth today. Only by opening your heart and accepting all the products of human beings can we find something more noble in human life.

Diamonds are made of carbon and pearls are constantly condensed in the shell, but we can't deny and abandon them just because we have carbon and pearls, they are still playing a role. We like pearls and diamonds, but we should also like carbon and shells.
