the notebook seems to have problems with showing graphs with Chinese texts (Unicode-like strings are displayed).

Thanks for the great work you have done. It helps me a lot in understanding the book better.

In Chapter 01, there is a sentence "也就是说，有能力为孩子提供平板电脑的学校比那些不能，不管药片如何处理" that appears to be unintelligible. It coule be "也就是说，有能力为孩子提供平板电脑的学校比那些不能的学校更好，无论它们是否提供平板电脑".

I couldn't get a url directly linking to the sentence, but if you search it, you should be able to easily find it.

I found that there are translate error in chapter 04 p1.2.
the origin text show's that.

"As a general rule, the dependence flow in the direct path from A to C is blocked when we condition on an intermediary variable B"

but the translated text is

"作为一般规则，当我们以中间变量 C 为条件时，从 A 到 B 的直接路径中的依赖流被阻塞。"

In fact the intermediary variable is B rather than C.
