Classical Chinese is an important cultural characteristic system in China. Foreign researchers need to know the local culture and the history of China, and they must learn to understand classical Chinese in order to obtain first-hand information.
In Cambridge University and Harvard University, there are a large number of scholars who know classical Chinese and have rich works, such as Fei Zhengqing, author of The History of China in Cambridge, Du Weiming of Harvard University, etc., all of whom are first-class scholars whose teaching level is higher than that of domestic professors. As for foreign folk, there are also many.
In fact, it's all a language, and anyone can take the time to learn it.
