There is a saying in the second volume of Chinese literacy class in grade one that "the ice and snow melt, and spring is Ding Dong". Is it "Ding Dong in Spring" or "Ding Dong in Spring"?

Director Chen of Linyi Teaching and Research Center told the reporter that the writing of "spring water" in primary school textbooks is correct. Since the 200 1 version of the Compulsory Education Curriculum Standard Experimental Textbook, the word "Ding Dong" has been changed to "Ding Dong". The two words "Ding Dong" and "Ding Dong" are universal and belong to special-shaped words.
