But anyone who had grown up in China and was proficient in Chinese would have no trouble reading it, and they would be able to understand its meaning quite well.
For translators, whether it was foreigners learning Chinese and then translating it, or Chinese people learning English and translating it... translation was enough to make anyone want to die.
Translating English into suitable Chinese or idioms was not actually difficult. As long as you knew enough Chinese idioms and understood what they meant, that was enough.
But if you wanted to translate Chinese idioms into suitable English or another language, anyone who had studied it probably knew that this kind of translation was truly enough to make you want to die.
Take the four characters "secretly march through Chencang," for example. Try saying that in English and see how many words it takes to explain clearly.
Academic papers might not seem to have many places where idioms were needed, and the places where they appeared might not seem especially important, but that was not really the case. It depended on how well you could organize language.
As for why Jiang Yan Hai had done this, the reason was simple. Weren't they just papers? Papers were not only an important means of communicating with foreign countries, but also of exchanging ideas with domestic peers and allowing later generations to keep learning.
So Jiang Yan Hai did not mind publishing some papers. Many of his papers had been discussed with Er Dan, and it could be said that they were full of solid material. Even domestic scholars at the academician level could probably learn something after reading them.
Of course, that did not mean Jiang Yan Hai had learned more than those academicians. His foundation and experience were certainly inferior to theirs,
