Wang Ruoping is the founder and editor-in-chief of the series of exam worms. I have passed TOEFL, IELTS and GRE, and I am doing English problems in the New Year's Eve. His family is just like us ordinary people. There is no diplomat at home, and he is not a returnee. His only trump card is hard work. According to him, he worked on the problem all New Year's Eve.
But he is different from the average bookworm. He is not a nerd. He studies with goals and emphasizes methods. Now, many tested memory trees for learning words from brothers and sisters are one of his research achievements.
But he is a little conceited, which is similar to Kim's style. Always scoff at some worldly things, but pay great attention to some details. There is no lack of humor in words, but it is often ironic to listen carefully.
