The "Zizhi Tongjian" is a very long book and requires a long time to read. The author was able to spend ten years, translating a little every day. I can also read 100 pages every day.
Gradually, one day I will also finish reading it. Don't be scared by the number of pages, nor be afraid that you won't be able to persist. Just keep reading 100 pages every day. Eventually, it will be finished.
Just like many things, you may not be able to do them immediately, but if you keep practicing every day, one day you will learn. Don't rush to eat a big meal all at once.
Reading this book "Huashan's Comprehensive Explanation of Zizhi Tongjian" will take some time. Your life also needs some time. Slow down, calm down, and complete it little by little.
