This wasn't about reading knowledge, it was about writing knowledge. The original poster was complaining about grammar errors in their own publications. And even learning reading knowledge of a language that is totally different from your own isn't so easy. I spent quite some time trying to learn Mandarin.

Also out of curiosity: How many languages that are not related to your native language can you fluently read?

There are millions and millions of people in Canada and the US that are fluent in both English and Mandarin. Hire one of them.
