Four tones. According to official website of Wuhan Education Bureau, the four tones not only examine students' necessary basic knowledge and skills, but also their abstract thinking and reasoning ability, and also their innovative consciousness and practical ability, which is more difficult than the senior high school entrance examination. In 2023, the four tones test in Wuhan will be divided into 10 subjects, namely Chinese, mathematics, English, physics, history, chemistry, biology, geography and political Japanese.
