Is it okay if I repeat my studies in Shaanxi Zhongyan for one year and only write about the first three years of high school?

Shaanxi China Tobacco reported for one year, but I only wrote that I couldn't do it for three years before high school. According to the relevant public information, it is necessary to fill in the educational background and educational background in the Shaanxi China Tobacco Registration Form. Only fill in the original three-year high school education and education, without explaining the reasons, it will affect the registration and recruitment qualifications.
