How high was Pu Yi's real level of education?

Puyi's true level of education is difficult to determine because he experienced political turmoil and war in his childhood and youth. He received a systematic education in Manchurian culture during the puppet Manchuria period, but as time passed, this education gradually disappeared, and his cultural level was affected. After Puyi became an adult, he received some education, including peace education in Japan and the Soviet Union and Puyi University. However, these education were all for military and administrative purposes and did not provide enough cultural courses. Therefore, Puyi's cultural level was relatively low. In Mein Kampf, although Puyi was a prisoner, he still had a certain level of cultural knowledge and could read books to understand some political and historical knowledge. However, this was only a fictional plot in the novel and could not represent Pu Yi's true cultural level.
