How funny would it be to see memes（表情包） in textbooks？ Some students from Chengdu No． 7 High School have made it come true．

    The students wrote a set of creative textbooks that includes five subjects﹣Chinese， English， maths， chemistry and physics． They share their notes to help students prepare for High School Entrance Exams in this way． Funny memes can be seen almost everywhere in their textbooks．

    Each textbook has its own style， too． The English textbook introduces films and TV series． The chemistry textbook has wuxia characters． There is a boy named Shangguan Huaxue in the book． He meets a girl and they learn chemistry together． It also has wuxia﹣style notes．

    Yan Zuhuai， a top student at Chengdu No． 7 High School， is the textbooks' editor﹣in﹣chief（主编）． He got the idea to create the books in June， 2017． "Many students wanted me to share my notes with them． When I saw people sharing bikes， I thought I could share knowledge， too．" Yan said．

    But after putting all of his notes together， he found them boring． Realizing that his classmates enjoyed online novels and memes， he decided to add those things to his notes． He wrote guidelines for each textbook and invited 13 students to join him in creating them．

    The final versions（版本） of the textbooks came out at the end of December． Many publishing houses have shown an interest in them．
