The key depends on the age of the child. If you are a sophomore, I recommend Neverland. Neverland is the Chinese version of Story Time, a British children's literature magazine. This magazine is very popular in Europe and America, and it is a great story magazine. There are various types of stories, including myths, fairy tales, fables, science fiction, adventures and so on. And the illustration is very nice, and the illustration level is not bad. If it is the third grade, you can consider children's literature and October literature youth edition. These two magazines are old-fashioned children's literature magazines, with a large amount of words and many novellas. Stories are basically original, which can exercise your reading ability.
