When did Zhang Xuefeng start talking about college entrance exams

In June 2022, the first live broadcast of the "Warm Mango Project", a campaign launched by Quark and The Public Welfare Times, went live, with Zhang Xuefeng, Quark's volunteer officer for the college entrance exams and a senior college guidance teacher, as the keynote speaker. The gaokao refers to China's higher education entrance examination, which is the qualification examination for candidates to enter and choose universities, and is also one of the most important national examinations in China.
