I've recently wanted to read "A History of the Twentieth Century" due to the Israel-Iran conflict, but kept procrastinating. Over the weekend, I remembered Luo Yonghao's newly launched Qieting, now called Yizu Tingku, and spent about 2.5 hours listening to this book.

The feeling it gave me was like having someone who has thoroughly read the book sitting next to you, explaining it bit by bit. The content is very rich and pleasant to listen to, far better than those "read a book in five minutes" short videos.

Especially for people like us who are constantly grinding in the trenches as Degens, who don't have much energy to read physical books, this is definitely worth using.

The app design style is very Luo Yonghao, consistent with the Smartisan OS design language.
