Despite, or perhaps because of, the pressure and stress put upon the young emperor, he despised learning for the majority of his life. According to Weng Tonghe's diary, the emperor could not read a memorandum in full sentences by the age of 16. Worried about her son's inability to learn, Cixi only pressured him more. When he was given personal rule in November 1873 at the age of 18 (four years behind the usual custom), the Tongzhi Emperor proved to be an incompetent ruler.
