As a student that is currently learning Chinese, the first sentence is true, from a Chinese perspective. The written language is extremely important for Chinese nationals; I've heard of all sorts of arguments from expats at my school, saying stuff like: "I just want to learn how to say X; when am I going to write it!?" Practically speaking, reading is much easier than writing (I can read way more than I can write) and once you hit a particular threshold of characters, you can read 90% of the text around you.
As for the second sentence, for a person with no background in tonal languages, learning the tones in Mandarin is extremely challenging. I assuming that the parent is a native English speaker. According to the Foreign Service Institute, Mandarin and Cantonese (you didn't specify what kind of Chinese) are among the hardest languages to learn for a native English speaker.[0]
I think Chinese (Mandarin and Cantonese) is difficult. And this is coming from a native English speaker with a background in Cantonese (my parents are from Hong Kong).
