On January 12, 2004, Si Xia, a national model worker and famous primary school teacher, passed away in Nanjing at the age of 94. After graduating from Hangzhou Women's Normal School in 1927, Si Xia successively taught in primary schools in Shaoxing, Jiaxing, Xiaoshan, Hangzhou, Zhejiang and Nanjing, Jiangsu. In the 1950s, she created the primary school Chinese literacy teaching method that "words do not separate from words, words do not separate from sentences, and sentences do not separate from text", which greatly improved the quality of literacy teaching. The students she taught knew more than 2000 Chinese characters and read 174 texts in two years, making her the first to none in the domestic primary education world at that time. In the 1960s, after summarizing and demonstrating by experts and scholars, Sixia's primary school Chinese teaching method, which "centers on Chinese teaching and combines literacy, reading, and writing", has had widespread influence across the country.
