Everyone's reading habits are different, and the traces of paintings in the book will also affect the reading efficiency and mood of others.
Different people have different views on the content of the book, and your views and traces are likely to affect others' thinking.
In addition, most libraries in China are banned. It would be a great shame if everyone left something behind when reading this book!
I don't understand foreign ones. After all, there are cultural differences, so it is a bit inappropriate to measure China by foreign countries.
I hope you have a happy and meaningful summer vacation!
