Application program for converting Chinese characters into regular script

B analysis: this question mainly examines students' accurate cognition and vertical reappearance analysis ability. Chinese characters have a long history and have a long development process: from the earliest ancient writing-Oracle Bone Inscriptions (bronze inscription)-the national writing in the Spring and Autumn Period and the Warring States Period-seal script-official script-regular script-running script, to the late Eastern Han Dynasty, calligraphy became an art. Cai Yong in the Eastern Han Dynasty was a famous calligrapher at that time. Zhong You of Cao Wei began to change the font from official script to regular script, which is the progress of China's calligraphy; Wang Xizhi of the Eastern Jin Dynasty was known as a "book saint" because of his extensive knowledge and excellent quality. His son Wang Xianzhi and Wang Xizhi are called "two kings". Therefore, the correct answer to this question should be B.
