There's no such thing as an easy language, all of them take hundreds/thousands of hours of work to get proficient in. Chinese, for the most part, is no harder than any other language. Whether it's easy or hard will depend on how similar it is (in terms of grammar and pronunciation) to your native language. 

Except for its writing system. Learning all those characters is undeniably very time consuming compared to learning a syllabary or alphabet. That said, it's 100% doable. If you want to learn Chinese, go for it. You can do it and it's worth the trouble. ;)

I have no clue why u wanna learn chinese,but just one advice : if u wanna study chinese at university
