NewCultivator if u wanna learn chinese mandarin, a good place to start is using the app Hello Chinese.
I learned mandarin for 4 years and the app basically summarized what i learned in those 4 years
Tho, if u have trouble with certain words, use pleco because its like a dictionary.
But you might also have trouble with chinese idioms as they are frequently used in novels and such so try to read on some famous proverbs, idioms, and sayings that they like to use.
