The TV series "Da Kao" was adapted from a real event. Taking the senior three students in Shexian County, Anhui Province in 2020 as the research object. Not only did I encounter the problem of masks, but I also encountered extreme weather on the day of the college entrance examination. Many sections of the county town are impassable. After discussion, it was decided to postpone the subjects of Chinese and mathematics in Shexian examination area. The scenes and characters in TV series are all based on real events, so they look real.
