As to the comments above on Chinese:

There are 2 forms of written Chinese; traditional or simplified.

Initially, there was only one written language, being the ancient and difficult traditional form. Then a few decades ago, the Chinese government decided to “simplify” the traditional writing to make it more accessible.

As a result, books sold in China are usually in simplified form. Books in Taiwan, Hong Kong, and overseas (catering to Chinese readers who didn’t learn to read in the simplified Chinese system) are in the traditional form.

I know a lady in her ’60′s who grew up Hong Kong, and she can’t read the new simplified Chinese, and I know a young woman who grew up in China, and she can’t read the old traditional Chinese.

The cover above looks like traditional Chinese.

Separately, there are multiple spoken dialects, like Cantonese, Mandarin, Hakka, Fujian, etc. Cantonese is a southern dialect. Mandarin was a northern dialect, and is now the official dialect of both China and Taiwan.

Dialects are different ways of pronouncing the same words, like someone reading a poem with a heavy Scottish, Texan, or Jamaican accent, to such an extent that it’s practically another language.

Dialects are completely separately from the written language. As a result, in China, people go to school in Mandarin and learn to read the simplified writing. In Taiwan, people go to school in Mandarin and learn to read the traditional writing. In pre-1997 Hong Kong, people went to school in Cantonese and learned to read the traditional writing.

Books don’t come in Cantonese or Mandarin, they come in traditional or simplified Chinese.
