The homophonic "rotten stem" frequently appears on campus, even affecting students' homework and test paper expression - how to correctly guide teenagers to use the homophonic word "strong winds can blow up a balloon, but cannot blow away a butterfly." Recently, Zhu Wenjie, a Chinese teacher at Pukou Primary School in Nanjing, Jiangsu Province, held a themed class meeting to guide students to use language and writing in a standardized manner, in response to the phenomenon of "rotten stem" appearing frequently on campus online. At the class meeting, Zhu Wenjie compared the child who followed the trend and said "rotten stems" to a hollow, non thinking balloon, guiding the children to be a butterfly with thinking and judgment, which sparked a warm response. The population of people who are exposed to online language is becoming younger and younger, and homophonic memes such as "Yalishan Da" and "cupware" frequently appear on campus, even affecting children's homework and exam expression, causing concern. How to correctly guide teenagers to recognize and use homophonic words requires thinking and attention. The principle and bottom line of using homophonic words have a long history as a rhetorical device. For example, in the Tang Dynasty poet Liu Yuxi's "Two Poems on Bamboo Branches, Part One", "the sun rises in the east and the rain falls in the west, and the road is clear but there is no clear" homophonic sound of "qing" and "qing". Since entering the era of the internet, people's language concepts have become more open, and homophonic means seem to have broken through a certain cage. They are not only widely used on the internet, but also permeate various scenarios from the internet. As a rhetorical device, homophones themselves are not inappropriate. Homophones have indeed enhanced the vividness, appeal, and artistic appeal of Chinese language in the process of its development. However, the rapid development of internet technology, the competition on self media platforms, and the value orientation of traffic being king have given rise to the phenomenon of irrational use of homophones. It is necessary to gather social consensus and clarify the principles and bottom lines of homophone use Wang Jiahe, a researcher at the Postdoctoral Workstation of the Language and Character Application Research Institute of the Ministry of Education, said. Avoiding the proliferation of "rotten stems" on campus conforms to the homophonic expression of public order and good customs, which can allow people to experience the strong vitality of Chinese language and writing to keep up with the trend of the times and continue to grow and develop. However, for teenagers who are still in the stage of language learning, the proliferation of homophonic expressions not only pollutes their language learning environment, but also has a negative impact on their subsequent language skill acquisition. 'Homophonic stems' sometimes involve changing the writing of words or using non-standard grammatical structures. If children use' homophonic stems' too much, they may misunderstand vocabulary and grammar rules, thereby subtly affecting their language understanding and subsequent development of expression ability, 'said Zhu Wenjie. In fact, children use 'homophonic memes' more out of curiosity and imitation. They may not be clear about the source and meaning of' homophonic memes', but may rashly use them because they believe that certain 'homophonic memes' can meet their needs to express emotions and attract attention. In this way, "homophonic memes" can easily spread quickly on campus, gradually forming a "rotten meme". If the level of homophonic expressions that are not high and can be used or not used becomes ubiquitous in society, the environment for using Chinese characters will become very chaotic, making language learners, especially primary and secondary school students, feel at a loss
