The day before yesterday, I went to the book fair. It's been a long time since I last visited. I feel that the book market nowadays is getting more and more modernized. There are a lot of books, colorful and flashy. Nowadays, times have really changed, and books have also become extravagant like movies and TV shows. However, I don't quite approve of this so-called superficial prosperity. Perhaps this is just a need for commercial operation, but books should not only be regarded as commodities, I think they carry more meaning - our寄托for knowledge and ourselves.
