Spanish may be easier for English speakers than Chinese speakers, just as it is easier for us to learn Japanese than foreigners.
But don't be afraid, because Spanish is very charming and sexy, and it is very practical in some places in the United States and Latin American countries except Spain.
I studied Spanish a few years ago. Like you, I started from scratch. Because of my love for Spanish, I learned it. I think the most difficult thing is the various forms of words, feminine and masculine, and the suffix of verbs should change according to the subject. These all need hard work, and the pronunciation of that R is really too difficult for China people.
In short, you should be proficient in the most basic grammar and various forms of commonly used verbs. If you want to talk more, you won't find a feeling if you don't talk.
