There are "five ones" in The Doctrine of the Mean: "erudite, interrogative, thoughtful, discerning and persistent", which means that you should study extensively, study carefully, think carefully, distinguish clearly and practice practically. Also translated as: extensive study, detailed study, careful thinking, clear distinction, practical implementation.

In my opinion, knowledge should be extensive, why should we ask more questions, repeatedly verify, distinguish between right and wrong, and practice hard can also be used as an explanation of the original meaning.

To apply the "five ones" to the carbon neutrality of the peak carbon dioxide emissions, we need to read the report of the Intergovernmental Panel on Climate Change carefully, because the carbon neutrality of the peak carbon dioxide emissions comes from the international climate change convention, and we need to ask more why. For example, why did the starting point of the first report be 1750 and the starting point of the sixth report be 1850- 1900? Does the carbon dioxide emitted by early industrialized countries count? Why is it possible that foreign languages are translated into Chinese mainly because of human activities? Why did the first report predict the temperature drop, while the current report only predicted the temperature rise? Another example is whether sunspot activity has an impact on climate change. The reason for asking more questions is that climate change is a scientific issue, and there are still many uncertainties.

For the carbon neutrality of the peak carbon dioxide emission, it is also necessary to repeatedly verify and analyze the road maps and construction drawings of various fields and places, instead of adopting a "one size fits all" approach to reach the peak. After all, from the perspective of resource endowment, development level, industrial structure and technical level, the foundations and conditions of different places are different. Only in this way can we achieve the goal of 3060.

It is necessary to unify the understanding and the top-level design of the central government, and also to take practical measures. Only by taking the right medicine can we achieve the expected goal and embark on a carbon neutral road with the peak carbon dioxide emission with China characteristics.
