Chinese is not composed of an overly intricate grammar but what makes it hard is that it's an analytical language, which does not always follow the rules or the structures taught from teaching materials, especially when it comes to colloquial expressions. The basic structure of Chinese is definitely SVO but that is not always persuaded as it could be SOV in some situations, just like Turkish; this is not something you might find in a proper Chinese grammar book but it's the way how would natives actually speak. For example, 饭吃了吗(OV), 你作业写完了吗(SOV), 帽子摘掉(OV. injunctive), 你把鞋子穿上(SOV), 我们把这部电影看了两遍(SOV), 他这三门语言都会说(SOV)or这三门语言他都会说(OSV)… I think SOV form in Chinese is more likely used in injunctive expressions whereas SVO form tends to be a declaration or a statement. I guess this is the tricky part that some learners don't know where is the right place to leave a preposition or an auxiliary; as you can see, not everything obeys the rules from books, and this is a common aporia among all the analytical languages.
