Kanji and romaji

Why are Chinese characters so fascinating?
My Chinese friend asked me a question:
As we all know, there are 7 days in a week, when you need to express the eighth day, how do you say it in English?

This stumps me. There is no such word in English. I can only say "Monday next week", or "the day after Sunday".

But the Chinese can create a new word "星期八" at will, and other Chinese people don't need to learn anything. The Chinese people can immediately understand what he means.

Another Chinese teacher asked me a question:
If you went back to England hundreds of years ago and asked Queen Anne: "What are trains, wires, televisions, refrigerators, telegraphs?"
Queen Anne will know nothing.

But if you go back 2000 years ago and ask Qin Shihuang the same question.
Qin Shihuang will tell you: Yes, I know the general meaning.
train: a vehicle powered by fire
Wire: A rope that can spread lightning
Television: A machine that displays shadows by means of lightning
Freezer: a box full of ice
Telegram: Reports sent by lightning

Since it was finalized 2000 years ago, the number of commonly used Chinese characters has dropped from 50,000 to 7,000, but its meaning has expanded countless times with the development of human science and technology.All professional words, including words that have not yet appeared in the future, can be expressed using these 7,000 Chinese characters.People can understand the meaning of these future words without detailed study.

But the number of English words has expanded to 1 million in the past 300 years, 98% of which are professional words that ordinary people cannot master. Basically, every time humans discover new knowledge and items, English needs to create a new word. Moreover, people who have not studied cannot understand it.

Chinese characters：This is a magical text whose underlying architecture can be infinitely expanded without incurring too much learning cost.
