Have you tried learning to write Mandarin?
This is not an easy language. If you want to be moderately literate, you are trying to memorize around 6,000 unique characters. Many of them are homonyms, so each time you write down a word, you need to figure out from context which one you are writing.
example:
ma ma qi ma.
ma man.
ma ma ma ma.
There are five different characters in the above tongue twister, pronounced six different ways. Four of the pronunciations are different versions of “ma”.
Not a simple thing to inflict on a kid.
