Zhixin High School (执信中学), located in the southern Chinese city of Guangzhou (Canton), was founded in 1921 by Sun Yat-sen in memory of his comrade, the democratic fighter Zhu Zhixin (朱执信), who was killed in action in a battle at Hu Men, Dongguan, at the age of 35. In the school campus, a symbolic tomb was built for Mr. Zhu. Since its birth, the school had been one of the most prestigious high schools in the country and had seen the graduation of many outstanding alumni over the years. In the early twentieth century, Zhixin High School has become one of the 37 key high schools in China. In 1994, it was graded as a First Level School of Guangdong Province.
