The radical dictionary is generally in grade three, and grade three is the next semester. The first grade mainly studies initials and finals, and recognizes syllables and tones as a whole, mainly pinyin. I started reading Chinese characters in my second grade, mainly learning simple Chinese characters. Of course, pinyin is also the main one. By the third grade, I basically had a certain understanding of pinyin and Chinese characters, so I began to learn to look it up in the dictionary. First I learned the word order search method, and then I learned the radical search method.
