Writing time is influenced by many factors, such as personal coding experience, writing speed, difficulty and depth of writing content, available research resources, etc. Generally speaking, in order to ensure the quality and accuracy of writing, rigorous research and repeated revision are needed to write the theoretical code of grounding gas with 35 thousand words. Specifically, it may take several months or even more than a year.

In the process of compiling, it is necessary to conduct sufficient literature research, collect relevant theoretical literature and case analysis, and sort out and classify the data. Then, it is necessary to analyze and think deeply about the research problems, formulate research methods, collect data and analyze them. On this basis, the coding work is carried out, and the content is sorted and revised step by step according to the research conclusion and demonstration process to ensure the logic, accuracy and organization of the paper.
