The current Linux 101 Ch01 documentation contains an outdated recommendation regarding the choice of image:

推荐选用和自己系统字长相匹配的镜像。如果不确定自己的电脑是 32 位还是 64 位,可选择 32 位版。

This recommendation may no longer be applicable to most users given the prevalence of 64-bit systems.

Additionally, a significant consideration to note is the decrease in performance when emulating a 64-bit system on a 32-bit system. This issue is elaborated on in this Zhihu article:

然而,承办学校有很多 32-bit 的 Windows 7,而在 32-bit 上模拟 64-bit 的性能非常堪忧——用户态的程序没法借用本地的页表,所以全系统都要模拟执行,而且内核模拟的负担也大了很多。
