Official website, Education Department of Hunan Province, introduced that Changsha is the capital city of Hunan Province, where students have better learning conditions and teachers have higher teaching level. Relatively speaking, the math test paper for the senior high school entrance examination is also relatively difficult. Secondly, the math test paper in Hengyang is relatively difficult, so the senior high school entrance examination paper in Changsha is more difficult than that in Yiyang.
