I don't find "learn about" to be the best translation for 了解, instead something like "understand": Would you like to understand Chinese history?
Nah man, it works https://en.m.wiktionary.org/wiki/了解
It's usually translated "learn about“, which includes the understand part.
Although it is a close way to say that in reality, 了解 actually does not mean to learn. The meaning is to understand, usually profoundly.
e.g. 他了解我 / He understands me well
Your example is correct, but 了解 has more than one meaning, in that sense. Here it usually translates to ”learn about“ which includes the understand part.
