Can intense brain activity hurt the brain?

Participants are not difficult to understand. How can it hurt their brains? In fact, our TV stations here can receive TV stations in Hong Kong, including Cantonese channels and English channels. I have been watching the Cantonese channel, so I can understand it naturally. If I watched the English channel as a simultaneous interpreter since I was a child, of course I could understand it. It is not difficult to translate them. It is said that it is difficult to satisfy vanity. Our English textbooks are too few to fully understand the history and culture of Europe, and those dialogues are unnatural. I have written a lot about the history of China and seldom about the history of the West, but it turns out that their history is also wonderful. I learn Chinese not only by a few Chinese textbooks, but all the information I come into contact with is presented in Chinese. There are many Chinese channels in TV stations, but it is difficult to learn English well only by those textbooks.
