Why does Puyi speak Mandarin?

Conform to society. Culture shock.

1. Adapt to society. At that time, Puyi did not understand Chinese characters and could not understand the Four Books and Five Classics. He made a joke that "what Weimin stopped" was regarded as "wanting to kill Yongzheng's head". Later, Puyi began to care about Sinology and learned Mandarin.

2. Culture shock. After the Qing Dynasty entered the customs, they were subjected to cultural shock. The language systems in various places were relatively messy. Some spoke Mongolian, some spoke Manchu, and some learned Chinese. When they arrived in Beijing, they simply merged with Beijing Mandarin. This became the common language used by the royal family of the Qing Dynasty, Beijing Mandarin (today’s meaning of Mandarin). Puyi naturally learned Mandarin.
